Very very very bad HRs. Very unprofessional HRs, they will disappear once you rejected without giving explanation.
They conducted 3 hr of System design round, very bad way of hiring. If you want to waste your time then please go ahead.
They can reject you even answering all the coding questions also the interviewers are not good, see lack of knowledge.
Interview process will be like this :-
1. Managerial round 30 mins
2. Coding very easy
3. System design very easy
4. Cultural fit
