A recruiter reached out via email.

I had an informational phone call with the recruiter about the process.

I was told that I could skip the online assessment because I had completed it in previous years (even though I never passed that stage back then).

I had two technical phone interviews of medium/easy difficulty.

I then received an email stating that I had to do a third interview for "more datapoints".

Given a string s and a substring t, find the indices of all occurrences of permutations of t in s.
