The whole hiring process took five years as I was rejected multiple times. However, as I gained more and more experience, the employer acknowledged that and invited me for an interview.

Upfront, consistent, and challenging. I received an email from the hiring screener for a call, followed by a take-home assessment and a panel interview. I didn't get the role, but they were professional and respectful.

If you have solved a decent amount of LeetCode questions, you will be able to solve the questions in the interview. The behavioral interview was detailed. For the coding rounds, be familiar with optimization techniques.
