The online assessment featured a string-based question, though I don't recall the specifics.

After passing the OA, the first round of technical interviews was conducted using CoderPad. Candidates were required to choose one of three programming languages: C, C++, or Java. The interview consisted of solving three problems within 90 minutes, all of which were basic problems at the LeetCode Easy difficulty level.

Previously, I had been using Python to practice problems for six months to improve my speed. I spent a week reviewing C++ before the interview. However, the results of the last-minute review were not as effective as consistent practice. I wasted a lot of time on basic syntax issues and compiling and debugging C++ code using CoderPad, resulting in only completing two questions within the 90-minute timeframe.

The interviewer was very kind and could tell I was not proficient in C++. He patiently helped me review C++ syntax.

Compare two version numbers. This was also a string manipulation problem.
