Interview is good, I have 3.7 years exp but I am unable to implement the first 2 questions remaining questions i answered well, however i got rejected , my suggestion is prepare concept along with coding and implementation of each and every concept example JWT implementation, retry mechanisms, singleton , threads etc..

Worst Interview Experience: The interview was scheduled on Sunday, and trust me it was the worst interview experience I ever had in my entire career. The interviewer joined 10min late, and asked to wait for 5 min so that he can check my resume full of background noise and he wasn't even interested in taking the interview. Started with intro of myself and the rest of the interview whereever i said I had just less knowledge on the particular skill he used to ask more on it, which was kind of fine whole interview went in a similar way . No clear questioning or clarity on what he wanted to ask and also explaintion of the questions weren't proper I really felt like dropping the interview in middle, the interview was irritating.
