Mastering Technical Interviews: Proven Hiring Strategies and the STAR Method

Recruitment Purpose

Technology drives business success, and engineers are a company’s most valuable asset. Hiring is therefore about selecting the best talent to achieve commercial goals.

What Kind of People to Hire?

Three critical factors are used to evaluate candidates:

Skills : Project experience and the ability to solve complex problems; candidates must not only complete work but excel at it.

Potential : A solid knowledge base, curiosity, and a track record of growth. Past achievements should substantiate future promise.

Soft Skills : Personality, execution, leadership, and the ability to integrate quickly, deliver results, and inspire teammates.

A practical benchmark is that a new hire should outperform at least 50% of peers at the same level.

Interview Methods

What Not to Do

Ask purely factual questions that can be answered by reading documentation.

Pose overly complex or abstract algorithm questions that are impossible to answer in a short interview.

Ask hypothetical “what‑if” questions that do not reflect real experience.

These questions rarely reveal a candidate’s true ability and waste limited interview time. Also, avoid trying to prove the interviewee inferior.

What to Do

Ask about concrete past experiences (e.g., specific mobile projects the candidate has built).

Explore the candidate’s problem‑solving approach and reasoning.

Listen more than you speak; let the interviewee narrate their story, then probe deeper where needed.

Conclude by asking the candidate what else they would like to add and whether they have questions for you.

STAR Principle

The STAR framework helps structure interview questions and answers:

Situation : The context of the task.

Task : The specific assignment received.

Action : How the candidate executed the work.

Result : The outcome achieved.

Interviewers should verify each component and watch for fabricated or vague stories.

Fake STAR Examples

Vague descriptions without measurable results.

Only expressing attitudes or opinions without concrete actions.

Hypothetical scenarios that cannot be validated.

Interviewers need to guide candidates to reveal the real facts.

Identification Techniques

Focus on the "What/How/Why" of each step.

Probe for detailed implementation choices, trade‑offs, and lessons learned.

Pay attention to details that demonstrate deep technical understanding.

Other Tips

Remember that interviews are two‑way: interviewers represent the team and must treat candidates respectfully.

Hire for the future, not just for immediate needs; consider long‑term team growth.

Use the interview as a mirror: strong candidates inspire new ideas, while weaker ones sharpen your evaluation skills.

How Technical People Can Keep Growing?

Continuous learning, solid knowledge foundations, and good habits such as regular reflection and summarization are essential. Seek role models, study their work, and consistently improve your skill set.
