Such a great experience.

Starting with Laura as the direct point of contact, all the way over to Nikola and Danilo, who were my interviewers.

Laura was so decent and tolerant in conversation, while Nikola and Danilo gave me a unique experience not only with the questions they provided, but also the way they encouraged me to find my absolute maximum in situations where I felt stuck.

Overall, a great month behind me - I would like every interview process to be like this :)

1. Sorting the array with K monotonously increasing and decreasing sequences (where K << N) in the most efficient way.

2. Finding any max path in a binary tree.

3. Designing a class for RandomizedSet with all operations working in O(1) - Insert, Delete, GetRandom.
