Lexmark International Software Developer interview questions

First round was HR interview, I was scheduled for a panel interview after my HR. The panel interview took too long around an hour and you will be asked by 3-4 panel interviewers for technical questions. I was not given an update weeks after my panel interview and I did not know my stand on the panel interview. Their HR seemed to have forgotten for whatever reason. I just consider this move as a red flag and very unprofessional for a large corporation. I've read similar experiences and to the recruiter, please do your job right.

First round was a coding round in which 4 medium level questions were asked to solve followed by 2 round technical interview . In technical interview 2 oops code and 2 SQL queries were asked but all of easy level.
