1st Round(online): English assessment, questions ranging from listening test to speaking test to fill in the blanks
2nd Rounder(in-person): Coding test, simple hash map based question, other people got simple string based question. Difficulty: Easy
3rd Rounde(in-person): Another English assessment, typical behavioural questions, for ex, "Your coworker is struggling with his work, what will you do". 5 questions in 25 minutes, 5 min per question. Difficulty: Easy, timing is your worst enemy here, try to write atleast 100-150 words.
Final round(in-person, the next day): Interview, 20-30 minutes, questions depend on the interviewer. Generally, they ask about your resume, and some basic CS fundamental questions(OOPS, SQL vs NoSQL, etc). Some people had Group Discussion as well. So really depends on the interviwer what they want to ask. Difficulty: Easy-Medium
