Having recently been through the technical interview process myself, I thought I’d share a few tips that may seem obvious but maybe they’ll help you out.
1. It’s MUCH better to say “I don’t know, but I can find out” than to spit out a meaningless word salad.
2. Do a little research on your interviewers on LinkedIn so you have an idea of the types of technical interests/skills they might focus on.
3. Review your own resume before your interview and mentally highlight something to discuss that highlights your skillset.
