Submitted resume online (no referral), emailed by recruiter a few days later. I have <1yr of work experience. I won't break my NDA, but I will give a synopsis of each interview.

As C++ was my chosen language, on my phone screen I got a question on pointers/copy-on-write strings. Then I was asked a heap-based algo question and some basic knowledge on data structures/runtimes for certain operations.

Did well on phone interview and was brought directly onsite at MTV.

Interviews:

1. Part one was basically a BFS. Part two was a bit more complicated, the optimal approach required a Union-Find (I verbalized this solution but didn't have time to implement it).
2. Problem related to flappy bird. My solution here was better than brute force but still non-optimal.
3. Greedy binary tree problem (LC Medium).
4. Two parter involving subarray sums, was still working through the second part conceptually when we ran out of time. (LC Medium/Hard)
5. Behavioural interview, nothing special here.

Got the call about two weeks later that they were making me an offer at L4. The best insight I can provide is to focus on your communication with the interviewer. Think out loud, explain your thought processes, and absolutely ask as many (relevant) questions as you can think of. I also gave myself ample time to code, and had working solutions for every problem (at least part one) fully written before the time was up. Good luck to everyone out there!
