GitHub Mid-level Engineer: recruiter call, Battleship LLD and a Number of Islands style question

The overall interview process was straightforward and took 6 weeks from start to finish.

Recruiter call

• It was a pretty chill conversation about my resume and they actually asked about my GitHub profile as well which I thought was funny. Luckily I have a lot of activity on my public profile so I had lots of projects to talk about.

Virtual Onsite

• This round consisted of two technical interviews and one cultural one.

• The first technical one was a LLD Battleship game which was tough and I found I was tight for time but I had been practicing a lot of LLD questions leading up to the interview so I was just able to get all the methods implemented. I also recommend doing it in Python so you don't have to type as much code as typed languages like Java.

• The next was a LeetCode question similar to Number of Islands which I had already practiced so I got it and the time and space complexity explanations done pretty quickly.

• The behavioral one was pretty straightforward asking me about how I felt about working remotely and if I had done it before. They also asked about my career goals so definitely worth thinking about that before.
