I had three rounds of interviews, all technical. The first was a online programming exam with a couple of questions from CS Theory (DB, OS) and two in-person interview, with the second interview considerably more difficult than the first.
Interview questions [1]
Question 1
1) Given a string, return another string after removing all duplicates except the last one. Example : abcadba should return cdba
2) Print a matrix in a particular pattern (spiral)
3) A pattern matching question based on Tries

There was 3 rounds, one debugging and logical reasoning, then 2 coding questions on coderpad and a final phone interview round. The process took a total of close to three weeks. Overall, long process.
