The first screening round was a HackerRank challenge. It included a question related to counting votes (hashmap and aggregation), which was fairly basic. I was told that I would be moving on to the next rounds.

There were three rounds with members from the team I was interviewing for. These involved fairly standard LeetCode questions. Knowing arrays, strings, and graphs should be sufficient.

The recruiters were very helpful and responded quickly, as I had different offers.

String manipulation.

Mostly about splitting and extracting required information.

Replace a row and column in a matrix with zeros and ones. This problem can be found on LeetCode.

Another problem related to arrays. Fairly standard.
