I interview during COVID (remotely). 1. Submitted my CV and Cover Letter online. It took about 2 months until they got back to me (because COVID disrupted things), saying I've been shortlisted for an Algorithms Interview. 2. The Algos Interview lasted for about 1 hour. They used a code-sharing platform where the interviewer can see your code, while also being on a videocall. There was only one problem similar to Leetcode's medium/hard problems. It's a bit more 'conceptual' (i.e. you don't have to run your code), but you're still expected to write correct code. Every time you solve the problem, the interviewer adds additional constraints to make it more difficult. I strongly recommend candidates to prepare by reading "Cracking the Code Interview" and solving leetcode problems. Few days after the interview I received an offer. There was no behavioural interview.

For the summer internship, I first completed a one-on-one online interview. After that, I was able to choose a date for an in-person interview. Throughout the process, I was provided with helpful preparation materials, which were a great resource. I was also able to ask questions beforehand about the interview format, and the recruiters were happy to explain what to expect. During the in-person interview, I was asked two programming questions. They were moderately difficult enough to assess problem solving skills, but not overly difficult.
