Immediately after applying, I was sent a CodeSignal automated coding assessment with four questions (two LeetCode easy, two LeetCode hard).

I got a perfect score and received an email from a recruiter asking to schedule a call.

I scheduled the meeting and sent a confirmation email, but the recruiter never called.

I reached out to see if everything was alright and asked if they were interested in rescheduling, but never got a response.

Please don't waste candidates' time with an automated coding assessment if you're just going to ghost them.

Given a list of time intervals (start time and end time), find the maximum number of overlapping intervals at any given time.
