A recruiter contacted me, stating she found my profile on GitHub. She asked for my CV, and then we scheduled a call.

During the call with the recruiter, I was asked popular questions about my previous experience and current projects. She also asked me about ten basic technical questions. After that, I had two phone interviews, which led me to the onsite stage.

During the onsite, I had four coding interviews and one on large systems design, as I was interviewing for a graduate position after university.

Unfortunately, I was rejected a week after the interviews, as the hiring committee decided that I lacked experience.

I have a question about valid parentheses in a string, and about possible string permutations.

The hardest problem for me was about an interval and water drops that fall on it. I had to count how many of them are needed to make the interval wet.
