Technical interviews can feel like a test you can't study for. They're not. Most interviewers are looking for the same few things, and you can prepare for every one of them. Here's what we tell the candidates we work with.
Before the interview
Read the job description like an engineer
Split it into three lists: the core stack, the problems the team is solving, and the soft skills they mention. Prepare one real example from your work for each item on the first two lists.
Practice out loud, not just in your head
Solving a problem silently and explaining it while you solve it are two different skills. Practice a few problems while talking through your thinking. Record yourself once. It's uncomfortable, and it works.
Prepare your project stories
Pick two or three projects you're proud of. For each one, be ready to explain the problem, your part in it, a hard decision you made, and the result. Numbers help: "cut build time from 20 minutes to 6" sticks in an interviewer's mind.
Check your setup
For video interviews, test your camera, microphone, and screen sharing the day before. Have your IDE open with a larger font. Close notifications.
During the coding round
- Repeat the problem back. Confirm inputs, outputs, and edge cases before you write anything.
- Start simple. Share a basic solution first, then improve it. A working answer beats a perfect half-finished one.
- Think out loud. Interviewers can only score what they can hear.
- Test your own code. Walk through an example and at least one edge case before saying you're done.
- It's fine to be stuck. Say what you're considering. Interviewers often give hints to people who show their thinking.
During the system design round
There's rarely one right answer. Interviewers want to see how you handle trade-offs. Start by asking about scale, users, and constraints. Sketch a simple design, then go deeper where the interviewer shows interest. Talk about what could fail and how you'd know.
During the behavioral round
Use a simple structure: the situation, what you did, and what happened. Be honest about mistakes and what you learned. Interviewers trust candidates who can talk about a project that went wrong.
Questions you should ask them
- What does a typical week look like for this role?
- How do you handle code reviews and releases?
- What would success look like in the first 90 days?
- What's the biggest challenge the team is facing right now?
After the interview
Send a short thank-you note within a day. Mention one thing from the conversation that you enjoyed. If you're working with a recruiter, call them right after with your honest feedback. It helps them push for you, or find a better fit if this one isn't right.
When you work with ITCrop Consulting, we run a prep call before every interview. We'll tell you what this specific team cares about, the format of each round, and what past candidates were asked. You won't walk in blind.
