Logical Round - some random logical reasoning rounds which the HR takes
Technical 1 - some kids from college take it with googling random questions and in expectation of the exact output , does not understand the javascript itself.
Interviewer should be experienced and atleast skilled to judge the skill of the candidate. I saw numerous negative comments here but I still applied for that. My honest suggestion is having 4 round of interviews with so much inexperienced staff is quite unfair. I would never recommend to apply here to anyone.
