I applied through a recruiter. I interviewed at Qualtrics
Interview
After a few calls talking about my CV and the company as well as the projects I was invited to take a test. It was an online test, live coding on HackerRank platform. It gives you only 1,5 hour to complete 3 tasks. The platform compiles incredibly slowly do don't make my mistake - code in your IDE and then copy-paste.
There is just too little time so if you don't type quickly while thinking then this is not for you.
Interview questions [2]
Question 1
Sort an array in a way frequency first eg. you have 2 3 2 1 4 5 1 you need to give 3 4 5 1 1 2 2 because 3 4 5 is only once then 1 is twice, 2 is twice.
You are given an array of numbers and need to find pairs which have the lowest difference between them and return those pairs SORTED by first and then second number. Eg 1 2 4 6 5 you should return 1 2, 6 5
