Bottomline Principal Engineer interview questions

I had applied for the role of Principal Engineer online on the company website. Received call on July 18th 2024 and the first round of technical interview was scheduled on July 31st 2024. My interview experience with the interviewer was good. The interviewer was humble and did not try to show their supremacy. It was so realistic and in fact the interviewer was allowed me to refer the reference material when I did not remember the certain class name/way of implementing. The interview is all about understanding your experience, your approach to solve the problems/situations and not about memorizing the nuances/jargons. The interviewer believed in this principle and accordingly drove the conversation. This is a very rare gem quality that you would see in interviewers. I would like to appreciate this gesture and quality. I was qualified for the second round with engineering manager. At the time of first round - I came to know about the expectation on the job and it did not match with my expectation on the role of a principal engineer. I clarified this with engineering manager in the second round and I did not proceed further citing the job role mismatch with my expectation.
