Interview process took around 4 week 1 round data structure (asked some irrelevant OS questions ) DS quetion were pretty basic around matrix 2nd android round Basic questions around handler recyclerview internal implementation customviews and kotlin 3rd round design Supposed to be a design round but was asked rubbish, interviewer was very unprofessional For last CTO round they made me wait for almost 2 weeks . Utter unproffesionalism
