Interview Process consist of 5 rounds, I reached till 3rd
1st round was 1-hour interview with one EM in org, it was about question on optimizing web app and some javascript related questions
2nd round was 2-hour coding round where they ask you to implement code for some logical question
3rd round was again coding round of 4-hour where they ask you to develop cloud storage app including developing the same in UI tech stack you don't know and also need to develop backend API which in fact I never worked
To sum it up interview process is very lengthy and consist of steps to find some magical candidate who can develop a whole new shiny app in just 4 hours in tech stack which he/she has never worked in his/her lifetime :)
