Very nice, but difficult as only one coding question was asked. However, if you have sufficient preparation, then you can definitely crack it. There was also a system design round.

After clearing the online assessment, you will be scheduled for two coding rounds and a system design round. If all rounds go well, you will proceed to the managerial round.

I was referred by a friend and received the test link via email a few days after applying. After clearing the interview, they called and said they had already filled the position internally. Such a waste of time it was.
