"Technical interviews are structured. Understanding what companies evaluate — and how — makes a measurable difference."
What Technical Interviews Actually Test
Most technical interviews evaluate three things:
1. Whether you can solve the problem 2. How you think through a problem when you're unsure 3. Whether you communicate clearly under pressure
The third point surprises many candidates. Interviewers rarely observe someone else write code in their day-to-day work — so your ability to explain what you're doing and why is a significant signal.
Stage 1: Resume / Screening Round
A recruiter or HR professional will verify your background and communicate the role.
Prepare to explain: - Your current or most recent role in 2–3 sentences - Why you're looking for a change - Your key technical skills and years of experience - Your location, notice period, and salary expectations
Be direct and specific. Vague answers slow things down.
Stage 2: Technical Assessment
Most companies use a combination of: - DSA (Data Structures & Algorithms) for product companies - Practical coding challenges for service companies - System design questions for senior roles
DSA preparation: - Practice problems on arrays, strings, hashmaps, trees, graphs, and dynamic programming - LeetCode medium-level problems are a reasonable benchmark - Focus on understanding patterns, not memorising solutions
System design: - Learn how to discuss scale, trade-offs, and component choices - Practice designing systems like URL shorteners, chat apps, or notification services - Read about distributed systems basics
Stage 3: Technical Discussion
You'll typically talk through your past work with a senior engineer or engineering manager.
Strong answers: - Describe real problems you solved - Explain trade-offs you made - Mention mistakes and what you learned
Weak answers: - "I worked on a team that built X" (no individual contribution) - Vague descriptions of technologies without specifics
Stage 4: HR / Culture Round
This is not a formality. Companies are checking whether your communication style, expectations, and approach to work fit their team.
Common questions: - Tell me about a difficult situation and how you handled it - What kind of team do you work best in? - What are you looking for in your next role?
Prepare honest, specific answers. Generic answers are worse than brief genuine ones.
One Practical Thing
Most candidates who get rejected from technical interviews do so because they stopped solving problems regularly once they got their first job. Keep coding. Even 30 minutes a day makes a difference over a few weeks.
