There are two rounds for this interview. The first round is mainly about Data Structures & Algorithms and fundamental computer science topics. It's to check how good you are at solving problems, coding, and if you know the basics. The second round is all about your projects and core subjects. They want to see how you use what you know in real projects, what you actually did, and if you understand engineering well. Together, both rounds look at your logic, technical skills, and how well you can explain and code solutions.

The interview was 45 mins long. First, I was asked to introduce myself and then explain one of my projects. Then, I got a coding question about deleting repeated elements from a linked list without using extra space. After that, I had to implement a stack, and then write a function to find the minimum element in a stack in O(1) time. Finally, there were some questions about my resume.

I interviewed for the Senior Software Engineer position at RingCentral. The interview was of medium difficulty, but I found the process to be somewhat unprofessional. There were a total of four rounds of interviews. Unexpectedly, a hiring manager round was scheduled without any prior notice or consideration of my availability. Despite completing all rounds, I never received any feedback on the outcome. Each time I attempted to follow up with the HR representative, I encountered delays and procrastination.
