Interview questions [2]
Question 1
Give me an example of a time you disagreed with the way a more senior member of staff was conducting business, and how you dealt with it.
1 phone interview - recruiter asked me after to send her my availability and she never gotten back to me. waste of time, followed up with her like 4 times.
three rounds, phone screen by managers, on site 1 hour, task 1 hour, final round 1 hour. technical and behaviour both, hard, tension. good experience, but stressed period.good culture, good development.
I had one superday of 4 interviews. Questions were mostly behavioral. Tons of variations on the main behavioral questions. One technical question but it was very light technical. No live problem solving. Felt more like a vibe check.
