Learn how to plan, design, and build a web app for HR teams to manage hiring stages, interviews, feedback, permissions, integrations, and reporting.
Learn how to plan, design, and build a web app for HR teams to manage hiring stages, interviews, feedback, permissions, integrations, and reporting.
Before you sketch screens or pick a tech stack, get specific about who you’re building for and what pain you’re removing. HR teams, recruiters, hiring managers, and interviewers experience the same hiring process very differently—and a “one size fits all” app often ends up pleasing no one.
Write a short problem statement that describes the current friction:
Aim for something concrete like: “Hiring managers can’t see where candidates are, and interviews take too long to coordinate.”
“Pipeline” could mean a simple stage list (Applied → Screen → Onsite → Offer) or a more detailed workflow that changes by role or location. Likewise, “interview management” might include just scheduling, or also preparation (who interviews, what to cover), feedback collection, and final decisions.
Capture definitions with a few real examples:
Compare building to an applicant tracking system you could configure. Building is usually justified when you need a unique workflow, tighter integrations, or a simpler experience for a specific company size.
If you do build, write down what makes your app meaningfully different (for example: “fewer scheduling loops” or “manager-first visibility”).
Pick 3–5 metrics tied to daily work, such as:
These goals will guide later choices like permissions, scheduling, and analytics (see /blog/create-reporting-and-analytics-hr-will-trust).
Before you design screens or pick features, get clarity on how hiring actually moves through your organization. A well-mapped workflow prevents “mystery steps,” inconsistent stage names, and stalled candidates.
Most teams follow a core path like: sourcing → screening → interviews → offer. Write that flow down and define what “done” means for each step (for example, “Screening complete” might mean a phone screen is logged and a pass/fail decision is recorded).
Keep stage names action-oriented and specific. “Interview” is vague; “Hiring Manager Interview” and “Panel Interview” are clearer and easier to report on.
Different departments will need different steps. Sales might include a role-play; engineering might include a take-home assignment; executive roles may require additional approvals.
Instead of one giant pipeline, map:
This keeps reporting consistent while still fitting real workflows.
For every stage, document:
Pay attention to where candidates stall—commonly between “screening → scheduling” and “interviews → decision.” These are prime spots for automation later.
List the moments where the app should nudge someone:
Tie reminders to stage ownership so nothing relies on memory or inbox archaeology.
An HR web application can quickly balloon into a full applicant tracking system. The fastest way to ship something useful is to agree on a tight MVP, then plan the next releases so stakeholders know what’s coming (and what’s intentionally not in v1).
Your MVP should let a team move a real candidate from “applied” to “hired” without spreadsheets. A practical baseline is:
If a feature doesn’t help move candidates through stages or reduce coordination overhead, it’s likely not MVP.
Create a simple matrix with “candidate throughput/time saved” on one axis and “build complexity” on the other. Treat these as must-have for v1: reliable pipeline status, scheduling that actually works, and feedback that’s easy to submit.
Push nice-to-have items (automation rules, advanced analytics, AI summaries) to later phases—especially anything that adds compliance or data risk.
HR teams rarely work the same way. Define what admins can configure from day one:
Keep configurations bounded so the UI stays simple and supportable.
Write a short set of user stories for:
These stories become your acceptance checklist for v1 and a clean phased roadmap for v2/v3.
A hiring app lives or dies on its data model. If the relationships are clear, you can add features (new pipeline stages, scheduling, reporting) without rewriting everything.
Plan a small set of “source of truth” tables/collections:
In practice, Application becomes the anchor for most workflow data: stage changes, interviews, decisions, and offers.
Candidates often apply to multiple jobs, and jobs have many candidates. Use:
This avoids duplicating candidate data and lets you track job-specific status, compensation expectations, and decision history per application.
For resumes and attachments, store metadata in your database (file name, type, size, uploaded_by, timestamps) and keep the binary files in object storage.
Notes and messages should be first-class records:
This structure makes search and reporting much easier later.
Add an AuditEvent table early to record changes to stages, offers, and evaluations:
This supports accountability, debugging, and HR trust when someone asks, “Why was this candidate moved to Rejected?”
Permissions are where HR apps earn trust—or lose it. A clear access model prevents accidental oversharing (like compensation details) and makes collaboration smoother.
Start with a small set of roles that match how hiring decisions are actually made:
Keep roles consistent, then allow fine-grained exceptions with “overrides” rather than creating dozens of custom roles.
Not all candidate data should be visible to everyone. Define permission rules per category/field, not just per page:
A practical pattern: most users can view the candidate profile, but only specific roles can view or edit sensitive fields.
Hiring is usually segmented. Add “scopes” so access can be limited by:
This avoids giving a recruiter in one region access to candidates for another.
Stakeholders will want to review profiles quickly. Provide controlled sharing:
This keeps candidate profiles inside your app instead of being copied into email threads.
A hiring app lives or dies on whether busy recruiters can understand status at a glance and take the next action without thinking. Aim for a small set of consistent screens with predictable controls and clear “what happens next” cues.
Pipeline board (Kanban-style): show each job’s stages as columns with candidate cards. Cards should surface only what’s needed to decide the next step: name, current stage, last activity date, owner, and one or two key tags (for example: “Needs schedule,” “Strong referral”). Keep the board focused—details belong elsewhere.
Candidate profile: one page that answers: who is this person, where are they in the process, and what do we need to do now? Use a clean layout: summary header, stage timeline, notes/activity feed, files (resume), and an “Interviews” block.
Job page: job details, hiring team, stage definitions, and an overview of funnel counts. This is also where admins adjust stage names and required feedback.
Interview calendar: a calendar view for interviewers and recruiters, with quick access to availability, interview type, and video/location details.
Every screen should highlight the top 3–5 actions: move stage, schedule interview, request feedback, send message, assign owner. Use a single primary button per view and consistent placement (for example: top-right). Confirm destructive actions like reject/withdraw.
Bulk reject, tag, or assign owner is essential for high-volume roles. Reduce mistakes with selection counters, “Undo” toasts, and safeguards like “Reject 23 candidates” confirmations plus optional reason templates.
Support keyboard navigation on the pipeline board, visible focus states, sufficient contrast, and readable form labels. Keep error messages specific (“Interview time is required”) and don’t rely on color alone to show status.
Interview scheduling is where hiring pipelines often slow down: too many back-and-forth emails, missed time zones, and unclear ownership. Your app should make scheduling feel like a guided workflow with clear next steps, while still allowing recruiters to override when reality gets messy.
Start with a few interview templates that cover most teams, and let admins customize later:
Each type should define default duration, required interviewer roles, location (video/in-person), and whether candidate preparation materials are required.
A practical scheduling flow usually needs:
Design for edge cases: last-minute interviewer swaps, split panels, or “hold” slots that expire if not confirmed.
If you integrate calendars, focus on two essentials: conflict checking and event creation.
Always include a manual mode: recruiters can paste an external meeting link, mark an event as “scheduled,” and track attendance without integration.
Reduce inconsistent interviews by generating a briefing pack per event. Include:
Link the pack from the candidate profile and the interview event so it’s reachable in one click.
Feedback is where a hiring pipeline management app either earns trust—or creates friction. HR teams need structured evaluations that are easy to complete, consistent across interviewers, and auditable later.
Create scorecards per role and per interview type (screen, technical, hiring manager, culture add). Keep each scorecard short, with clear criteria, definitions, and a rating scale (for example 1–4 with anchors like “no evidence / some / solid / exceptional”). Include an “evidence” field so interviewers describe what they observed rather than writing vague opinions.
For an applicant tracking system, scorecards should be searchable and reportable so they can feed an HR analytics dashboard without manual cleanup.
Interviewers often need a scratchpad. Support:
This reduces accidental oversharing and supports role-based access control: recruiters may see everything, while a cross-functional interviewer may only see what’s relevant.
Late scorecards delay decisions and candidate scheduling. Add automated nudges: a reminder after the interview, another before a decision meeting, then an escalation to the hiring manager if feedback is still missing. Make deadlines configurable by stage in the recruiting workflow.
Create a decision view that summarizes signals: average ratings by criterion, strengths/risks themes, and “missing feedback” alerts. To reduce anchoring bias, consider hiding other people’s ratings until the interviewer submits their own, and show evidence snippets alongside scores.
When designed well, this module becomes the “single source of truth” for hiring decisions and reduces back-and-forth in chat and email.
A hiring app can have a perfect pipeline and still feel slow if recruiters can’t communicate quickly, find the right candidates, and keep a clean record of what happened. These “small” tools are what make teams actually adopt the system.
Start with a few reusable email templates for the moments that repeat every day: application confirmation, interview invite, follow-up, request for availability, and rejection. Keep templates editable per role/team and allow quick personalization (name, role, location).
Just as important: log every message. Store a clear sent/received timeline on the candidate profile so anyone can answer, “Have we contacted them yet?” without digging through inboxes. Include attachments and metadata like sender, time, and related job.
Make candidate status updates easy, but standardized. Offer a controlled list of rejection reasons (for example: “salary mismatch,” “skills gap,” “not available,” “withdrew”) with optional notes.
This helps with reporting and reduces accidental wording differences across the team. Also separate internal-only fields from what’s shared externally—rejection reasons may be for analysis only.
Add flexible tags for skills, seniority, languages, clearance, or sourcing channel. Then pair it with fast search and filters recruiters naturally use:
Aim for “find in 10 seconds” on both a single job and across all roles.
HR teams still live in spreadsheets. Provide CSV import for backfilling candidates and CSV export for audits, sharing shortlists, or offline reviews. Include field mapping, validation (duplicates, missing emails), and an export that respects permissions.
Later, these same tools become the backbone for bulk actions (bulk email, bulk move stage) and smoother day-to-day operations.
Hiring apps handle some of the most sensitive data a company collects: identity details, resumes, interview notes, and sometimes equality or health information. Treat privacy and security as core product requirements—not a checkbox at launch.
Start by documenting what regulations apply and what you must be able to prove later. For many teams that means GDPR / UK GDPR, plus local employment rules.
Be explicit about:
Minimize the fields you collect by default. If a piece of information isn’t needed to evaluate a candidate, don’t ask for it.
When you do need sensitive data (for example: diversity monitoring, accommodations), keep it separate from the main hiring record and restrict access tightly. This reduces accidental exposure and supports “need-to-know” access.
At a minimum, encrypt data in transit (TLS) and at rest. Pay special attention to attachments (CVs, portfolios, ID documents): store files in a private bucket with short-lived signed URLs and no public access.
Control downloads and sharing:
Build an access log that records who viewed or exported candidate profiles and files, with timestamps. HR teams often need this for investigations and audits.
Also plan operational workflows for data subject rights:
Good compliance design makes the app easier to trust—and much easier to defend during audits.
Reporting is where an HR web application either earns confidence or creates endless “can you double-check this?” messages. Aim for analytics that are easy to verify, consistent over time, and clear about what each number means.
Build around pipeline health and speed:
Show these per job, because each role has different realities. A high-volume support role and a senior engineering role shouldn’t be forced into the same benchmark.
Provide two levels of views:
Keep filters simple and predictable (date range, job, department, location, source). If a filter changes a number, make that obvious.
Most reporting disputes come from unclear definitions. Add tooltips or a small “Definitions” drawer that states:
When possible, let HR click from a metric into the underlying candidate list (“Show me the 12 candidates in Onsite > 14 days”).
Enable exports that match real workflows: CSV for spreadsheets, PDF snapshots for updates, and scheduled email reports. Include filters and definitions in the export header so numbers don’t lose context when forwarded.
If you want a single north-star view, add an /reports page with saved report templates (for example: “Quarterly Hiring Review” and “Diversity Funnel (if enabled)”) that HR can reuse without rebuilding charts.
Integrations and rollout decisions can make or break adoption. Treat them as product features: clear scope, reliable behavior, and ownership for ongoing support.
Start with the systems recruiters already live in:
Define what’s “source of truth” for each data type (candidate profile, interview events, offer docs) to avoid conflicts.
Even if you integrate later, design now:
Focus on failures that frustrate HR teams:
If your goal is to validate the workflow quickly (pipeline board, scheduling, scorecards, and permissions) before investing in a large engineering effort, a vibe-coding platform like Koder.ai can help you get to a working internal app faster. You describe the recruiting workflow in chat, iterate on screens, and generate a React-based web app with a Go + PostgreSQL backend under the hood—then export the source code when you’re ready to take it in-house. Features like planning mode, snapshots, and rollback are especially useful when you’re testing early MVP assumptions with HR stakeholders and need to move quickly without losing stability.
Start by naming 2–4 primary user groups (HR admins, recruiters, hiring managers, interviewers) and write one concrete pain per group.
Then draft a one-sentence problem statement you can test with stakeholders, like: “Hiring managers can’t see candidate status and interviews take too long to coordinate.”
Write down:
This prevents “mystery steps,” inconsistent stage names, and stalled candidates.
Create:
Keep stage names action-oriented (e.g., “Hiring Manager Interview” instead of “Interview”) so reporting stays consistent.
Pick 3–5 metrics tied to daily behavior, not vanity charts:
Use these metrics to guide later decisions about permissions, scheduling, and analytics.
A practical MVP supports a full hiring loop without spreadsheets:
Defer advanced automation and AI features until the core loop is reliable.
Model Candidate and Job as separate entities, and use Application as the workflow anchor.
This handles the many-to-many reality (one candidate can apply to multiple jobs) while keeping job-specific stage history, interviews, and decisions tied to the right application.
Start with a small, consistent role set:
Add field-level protections for sensitive data (compensation, private notes, EEO/diversity data) and support access scopes by department/job/location to avoid overexposure.
Use a guided flow:
Integrate Google/Microsoft calendars for conflict checks and event creation, but keep a manual fallback for teams without integrations.
Use short, role- and interview-type-specific scorecards with clear criteria and a simple rating scale.
Separate:
Add reminders and escalation when feedback is overdue, and consider hiding others’ ratings until submission to reduce anchoring bias.
Make every metric clickable down to the underlying candidate list and publish definitions for key calculations (stage entry rules, handling withdrawn/rejected, on-hold timing).
Support practical exports (CSV/PDF) and saved report templates so stakeholders can reuse consistent views. For more detail on analytics design, see /blog/create-reporting-and-analytics-hr-will-trust.
