Interview
The process was pretty straightforward. It was a30 min interview with the hiring manager followed by an OA, a 1hr technical interview then a superday with a 1hr behavioral interview and a 1hr technical interview
no live coding with some oop and behavioral questions. the interviewers were very patient. the technical interviewers are usually young people under the age of 30, so just be chill and genuine with them and you’d be fine.
