Educative (WA) Software Engineer Interview Questions
& Process

It was the first round, basically a screening round where some senior engineer came, and asked me leetcode medium questions to solve with him. First, they asked me the a fibonacci series question, it was easy but the way he framed it and asked to return output was actually a bit confusing and i messed things up a bit. He wanted me to return the nth fibonacci number. The function would be passed a number n, and we would have to return that specific fibonacci number. I messed up when i ended up going one iteration ahead than what was required. it was on paper. The second question was a bit difficult, he asked me to return the nth largest number from a binary search tree without using recursion or a stack. Because, he wanted me to have O(1) space complexity. There was a bit complicated algorithm behind it which i didn't know at that time, hence, I couldn't do this question. My way of trying to reach the solution was a bit flawed too.

For a Software Engineer, they follow a three-round process: The first interview is a technical interview to screen candidates. Next is a full loop, which consists of 3 back-to-back 1 hour technical interviews. Finally, an Interview with the CTO.

I found the job on LinkedIn and applied online. After two days, I got a call for the first round. This interview was with a senior software engineer and lasted about an hour. I was given two coding questions to solve in Google Docs. They also told me about the company and its tech stacks. Twelve days later, I got called for round 2, which was a full loop coding round with three interviews back-to-back. Each interview had two coding questions. Three days after round 2, I got a call for the final interview, which was a week after the coding round. This last interview was with the VP of Engineering. The HR team was really helpful throughout and scheduled interviews around my commitments. The interviewers explained the questions well. Overall, it was a great experience, 5/5.
