Full Stack Developer interviews — common questions

Who is this Full Stack Developer interview plan for?
It is written for the interviewer, not the candidate: the hiring manager, engineer or panel member running the Behavioral Interview round for a Full Stack Developer role. It gives you a 60 min script to follow in the conversation — 6 questions with what each one is for and the signals to score against — so you are not writing the round from scratch the night before.
What does the Behavioral Interview round assess?
This round is focused on: Communication, Teamwork, Adaptability, Work Ethic, Learning Agility. It works through Communication and Teamwork, Adaptability and Problem-solving and Work Ethic and Task Ownership, scoring against 32 observable signals, with follow-up prompts on all 6 questions for going deeper where an answer is thin.
How is the 60 min split up?
The plan times 50 of the 60 min: 5 min opening, 40 min on 6 questions and 5 min closing. The questions take in Communication and Teamwork (15 min), Adaptability and Problem-solving (15 min) and Work Ethic and Task Ownership (10 min). The timings are there so the round stays on schedule and every candidate gets the same shape of interview — which is what makes two candidates comparable afterwards.
