Very immature in term of processes and handling candidates. All total had 4 rounds of discussion 2 on call and 2 face to face. 1 round - i think it was initial telephonic screening. 2 round- interactive coding round to write a debounce funtion etc etc 3. f2f - this guy was decent and asked proper Frontend related question like how to design analytic for single page app etc. 4. This was something unexpected, this guy may be nothing to do with UI, came for the interview just to satisfy his ego it seems. Asked very irrelevant and stupid questions and probably the reason i turned off thinking I should not be working with this guy, pathetic. Overall office atmosphere was looking good and cool, it was a apartment setup. My sincere advices to HR to be little polite with candidates and if you calling a senior candidate you must have a proper panel. All the best for you search.
