The interview process consisted of three rounds. The first round involved solving the "Letter Combinations of a Phone Number" problem from Leetcode. The second round involved solving the "Multiply Strings" problem from Leetcode. The third round involved solving the "Permutations" and "Summary Ranges" problems from Leetcode. The interviewer also asked to design a unit conversion system, including database design. I had a negative experience with the recruiters. I had to follow up multiple times for updates and scheduling for the next round. They contacted me from office landline numbers, making it difficult to reach them. I had to rely on email or LinkedIn for communication. I rejected the offer due to an unsatisfactory negotiation and a negative experience with the HR team.
