I applied through LinkedIn Easy Apply, and the recruiter reached out and invited me to an on-site interview—one round of interviews. Questions about your personal project and medium leetcode, as well as questions on how to optimise it.

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.
