I took a screening coding exercise through HackerRanks' jobs page (https://www.hackerrank.com/jobs/search). Hiring manager was in contact with me shortly after (a day or two later) saying I had done well in the exercise and that they wanted to follow up. I let him know that I needed to move quickly because I was at the latter stages with another company or two. He was very diligent in moving me quickly through their interview process, once even scheduling an interview on a Saturday instead of the coming Monday to expedite the process. I was also brought onsite and everyone was friendly. Onsite, I had more culture fit questions and algos/data structure questions.
