You have to start with the screening interview. The screening interview turns out great. I like the senior guy, Boon, he looks approachable. The guy you like to work with. Next comes the coding challenge. It was easy. On the technical interview, there were two interviewers and they looked intimidating. The technical interview focuses on your coding challenge. It is like creating a program and you defend it like a college student. They make me looked stupid. It was my first technical interview after my 2-year career break. I put on much effort for the coding challenge and how to expand it, that I lose sleep. And because of that, my communication was a bit impaired. Even, misusing the word subset instead of superset. Also, if you explain I think it would be best to present it visually like sharing your screen. That way it will be easy for you to explain. Especially, if you're a visual or kinesthetic learner rather than auditory. My advice to candidates. Don't use terms that you don't know how to defend. Avoid talking extra stuff. Like for example if you mention X, make sure you know its advantage and disadvantage. Everything you say, they will ask you back, even if it's self-explanatory. Prepare and prepare really, really hard. And do not lose sleep.
