It was a long process, like 6 rounds in total. Most of the interviews were well-organized, and the difficulty was pretty high, too. However, one of the interviews was a bit of a letdown because the interviewer seemed unsure about why I was there. Ultimately, I didn't receive an offer.

Technical Coding
There was a container that is open from both ends and that always is in sorted order. To insert an element, its position is determined, then each of the elements to the left or right of that position is removed. The new element is inserted, then the removed elements are added back. Each removal or insertion is an operation. Determine the minimum number of operations after inserting a list of integers into an empty list.
Confirmed questions1 question
- Is it possible to determine the minimum number of operations after inserting a list of integers into an empty list, given a container that is open from both ends and always remains in sorted order? For insertion, we determine the position, then remove elements to the left or right, insert the new element, and then add back the removed elements. Each removal or insertion is an operation.
