What kinds of interviews does Interview Coach cover?

All the spoken rounds, for any role and field: behavioral / 'tell me about a time' questions (STAR, CAR/CARL, SOAR, PARADE), the 'tell me about yourself' opener, motivational and self-awareness questions like 'greatest weakness', competency-based interviews, and role-specific experience questions. It calibrates the questions and the scoring bar to your exact role and seniority. It does not grade live coding or system-design — it coaches how you present your experience and judgment.

What is the STAR method for behavioral interviews?

STAR is a four-part structure for answering behavioral ("tell me about a time when…") questions: the Situation you faced, the Task you owned, the Action you personally took, and the measurable Result. It keeps your story clear and shows the interviewer your impact.

How do I prepare for a behavioral interview?

Practice answering real behavioral questions out loud using a structure like STAR, then get honest feedback on where each answer is vague, missing a result, or says "we" instead of "I". Interview Coach runs mock interviews and scores your answers against the real hiring bar so you can fix the weak spots before the real thing.

How much does Interview Coach cost?

There is a free STAR-method demo that scores an answer instantly with no account. The full coach — unlimited adaptive coaching that remembers your weak spots — is a one-time $29 pass for 30 days, versus subscriptions elsewhere that run $79–148 a month.

Does it work for non-technical interviews?

Yes. It calibrates to whatever role and field you name — nursing, sales, teaching, retail, new grad, career switcher — not just engineering. The behavioral interview bar applies across fields.

Behavioral Interviewing (Behavior Description Interviewing)

A structured interview approach built on the premise that past behavior is the best predictor of future behavior, asking candidates to describe what they actually did in specific past situations rather than what they would hypothetically do.

When to use it

Past-tense behavioral prompts — 'tell me about a time you...', 'give me an example of when...', 'describe a situation where...'. Answers are best delivered with a story framework like STAR or PAR/PARADE so each example has situation, action, and a measurable result. Research basis: structured past-behavior (BDI) questions predict job performance and out-predict hypothetical 'situational' questions for higher-level, managerial roles (Huffcutt et al.; Krajewski et al.) — the empirical reason a senior answer names a real past result, not a hypothetical.

The structure

Interviewer asks for a specific past incident tied to a competency (the Behavior Description Interview / PBDI form, Janz 1982).
Candidate selects ONE concrete, real past example (not a hypothetical, not a habit).
Candidate structures the answer: Situation/Task -> Action (the bulk of the answer, ~50-60%) -> Result.
Candidate quantifies the result and, ideally, names a takeaway.
Interviewer probes follow-ups ('what exactly did you do', 'why') to confirm the example is real and personal.

Strong vs weak

Strong

Question: 'Tell me about a time you handled a conflict on a team.' Answer (STAR): Situation — two senior engineers on my team were blocked for two weeks arguing over which database to use, stalling the release. Task — as tech lead I had to unblock the decision without losing either person. Action — I ran a 90-minute spike where each prototyped their option against our real query load, set three objective criteria up front (p95 latency, migration cost, on-call burden), and we scored both. Result — Postgres won on two of three criteria, both engineers signed off because the data decided it, we shipped four days later, and I reused that 'decide with a timeboxed spike' pattern on two later disputes.

Weak

Question: 'Tell me about a time you handled conflict.' Answer: 'I'm generally a really good communicator and I always try to see both sides, so conflicts usually resolve themselves when I'm around.' (What's wrong: it's a hypothetical/trait claim, not a specific past incident with an action and result, which is exactly what behavioral interviewing is designed to screen out.)

What the coach scores

Answer is a single, specific PAST event, not a hypothetical or a generalization.
Candidate's own actions are clear and use 'I', not just 'we'.
Result is concrete and quantified where possible.
Example actually maps to the competency being probed.
Holds up under follow-up probing (details are consistent and real).
Action portion dominates the answer over scene-setting.
