For me, it felt like they were trying to pretend to be nice and careful. (Or maybe they really were trying?). The bottom line is it was a very bad experience. All day long, you feel like a military candidate who has to take many tests one after the other with not enough breaks in between, including a written one on paper! They basically invite some 30 candidates per day with the goal that the bar would be something like 10% upper. From my perspective (after going through several interviews in my professional career), they treat candidates with arrogance. It’s kind of ridiculous how they love themselves and think they are the best company. In reality, their product isn’t that complex nor interesting, in my opinion, and they have to improve their attitude towards candidates.

100% of the questions in this company are not new and can be found here on Glassdoor.

I did not prepare well and got to the last technical interview. In the last interview, they like to ask "analytical capabilities questions," which, in other words, are mostly some sort of probability question.

The written part included:

• LRU
• Removing items from a given list
• Shuffling an array
• A question involving strings and hash maps

All three can be found on Glassdoor's previous posts.

The first technical interview was about data structures that can calculate sums in log(n) using a BST (also found here).

The second technical interview was to create a rand7 from a rand5 function.
