J'ai postulé en ligne. J'ai passé un entretien chez Roblox en févr. 2021
Entretien
Was sent a HackerRank test through email and was given 90 minutes to complete it anytime within the week. First problem was not bad. The next problem took most of my time and I didn't finish it. The last problem was probably the same difficulty as the second, but I had no time left.
Questions d'entretien [3]
Question 1
Given a 2D array keystrokes (first element: integer, encoded letter i.e. 0 – a, 1 – b, etc. Second element: integer, time it took to press key after previous key). Times sorted ascending order. Return the letter with the slowest time
Given 2D array of grid values for each row and a maximum value, find the max size square where the sum of the values is less than or equal to the maximum value. Ex: Given [ [1, 1, 1], [2, 2, 2], [ 3, 3, 3] ] and max value of 27, what is max size square?

I interviewed twice for this position. I passed the online OAs which included four tests, and was invited to a technical interview online. The first interview was two reasonable LC easy-mediums which had two parts each. However, I could not complete the second part of the second question. When I re-interviewed with them two months later to try again, the question bank got way more difficult, involving LC med-hards. I could not complete the questions the second time around, and I imagine you would have to basically memorize these answers to be able to do them on the interview in an hour each.

First part of the interview was 2 different cognitive assessment, both hosted as Roblox games. First involved trying different combinations of car assemblies to pass different obstacle courses. Second involved optimizing a factory production line.
The second part of the interview takes you through a bunch of different workplace situations, and asks you to assess the least and most effective ways to address them from a list of options.
And finally, you are asked to complete two leetcode like questions on CodeSignal. One was about medium and one was hard.
