ING Developer Senior interview questions

Got a home assignment that was quite time consuming and had to complete it in 3 days. My solution was not perfect, but I got an invitation to the technical interview. The questions were moistly easy and average. There was also an easy leetcode problem during the interview. The interviewers were mostly kind and accomodating. After some days I've received an offer.

It was the worst interview for me because of the fact that interviewers were unaware of what I have implemented.interviewer has asked many abnormal questions to me.Even if he was not able to reply his questions , he has refused my solutions.ING Bank is generally choosing low-level experienced developers for interviews and they are not fully qualified to evaluate candidates
