Pre-interview checklist
0 of 6 doneQuick tip
Open with your reasoning, not your answer. Technical interviewers hire people they can follow, so think out loud and name your trade-offs.
The PaxSigna view
In technical hiring, the strongest candidates are rarely the ones who know the most. They are the ones who can explain what they know, clearly, under pressure.
The full guide
Built for technical hiring, where how you think matters as much as what you know.
01 · Before
The more prepared you are, the calmer you will be. Set yourself up before you walk through the door or join the call.
02 · Technical
Coding rounds, design reviews, lab discussions and case problems. Learn to show your reasoning, not just your answer.

03 · Virtual
Technical setup and professional presence for online interviews. What the camera sees matters as much as what you say.

04 · On-site
From reception to the plant floor or lab, how you carry yourself sets the tone before the first question is asked.

05 · Questions
Good questions show you are evaluating the role too. Prepare several that prove you understand the work.

The STAR Method
Behavioural questions reward clear, specific stories. STAR keeps yours credible, concise and easy to follow, whatever you are asked.
Situation
Set the scene with just enough context for the interviewer to understand what was at stake. Two or three sentences is enough. The situation is the setup, not the story.
Pro tip: name the system, the team size or the timeline. Concrete details make your story believable.
Task
Say what you were personally responsible for. Interviewers need to know your role, not the team's, so be clear about what was yours to solve.
Pro tip: use I, not we. Credit the team elsewhere, but make your own ownership obvious.
Action
This is the core of your answer. Walk through the specific steps you took and why you chose them. For technical roles, name the trade-offs you weighed and the tools you used.
Pro tip: explain your reasoning as well as your actions. It shows how you think, which is what is really being assessed.
Result
Close with the outcome and, wherever you can, put a number on it. Then add what you learned or what you would do differently next time.
Pro tip: latency, uptime, yield, cost or time saved. One measurable result is remembered long after the answer ends.
Live example answer
“Describe a time you resolved a critical system failure under pressure.”
Situation
Our data pipeline started dropping events during a product launch, and dashboards showed stale numbers for about a third of our customers.
Task
As the on-call engineer, I owned finding the root cause and restoring data integrity before the next business day.
Action
I traced the drops to a consumer lagging behind a schema change, rolled the change back, replayed the missed events from the log, and added an alert on consumer lag.
Result
Data was fully restored within five hours, and the new alert has since caught two similar issues before they reached production.
Avoid the pitfalls
Small missteps can outweigh strong qualifications. Awareness alone puts you ahead of most candidates.
01
If you cannot speak to their products or the role's context, you signal that this is one of many applications.

02
Opening with salary can signal that pay is your main motivation. Let the employer raise it, or wait for an offer.
How to fix it →
03
Interviewers assume the same will eventually be said about them. Keep your past context professional and objective.
How to fix it →
04
Calling yourself a strong problem solver proves nothing. Employers believe examples, not claims.
How to fix it →
05
Saying you think they have covered everything signals passive interest. Prepare at least three questions.

06
A short thank-you within 24 hours is rare enough to stand out, and it keeps you front of mind.

After the interview
How you follow up can be the difference between an offer and silence.
Step 1
Within 24 hours. Reference something specific, make it personal and keep it brief.

Step 2
Write down what went well and what to sharpen while it is still fresh.

Step 3
If the timeline they gave has passed, send one polite follow-up. Just one.

Step 4
An offer starts a conversation. Know your numbers before you see theirs.

Technical rounds test how you think as much as what you know. Expect problems to be open-ended on purpose.
Pro tip:A correct answer reached silently scores lower than a good approach explained clearly. Interviewers need evidence of how you reason.
