I applied through an employee referral. The process took four weeks.

I cleared all tech and design rounds, but one person rejected me during the final fitment round. They asked me to design complete WhatsApp in a one-hour interview. The fitment round interviewer did not pay attention to my answers. It was a waste of time.

The process consisted of the following rounds:

• Design round: They asked about PCB design.
• Tech round: All Android questions.
• DSA round 1: Problems from GeeksforGeeks.
• DSA round 2: Problems from GeeksforGeeks.
• Fitment round.

The questions were:

• Maximized partitions of a string such that each character of the string appears in one substring, which can be found at https://www.geeksforgeeks.org/maximized-partitions-of-a-string-such-that-each-character-of-the-string-appears-in-one-substring/.
• Print all combinations of balanced parentheses, which can be found at https://www.geeksforgeeks.org/print-all-combinations-of-balanced-parentheses/.
• Design a WhatsApp application.
