I was contacted by the hiring manager on LinkedIn by email. We set up a call and had a quick chat. He mostly talked about the company and what they do and asked me some general question about what I do in my current role.

Then I had another phone call with the recruiter, again nothing particular, mostly general stuff like willing to relocate and such.

Then I had a phone screen, and was asked to code a simple question.

Then after that there was a second phone screen longer than the first one, which was again a coding question, followed by an open-ended design question.

Nothing difficult.

Check in brackets are properly closed. (first only (), then extend it to include {} and [])

Search engine (given a snapshot of web, how would I design a system to do simple search queries.
