Consisted of an online interview through HireVue (two Leetcode questions) and a Hackathon. I would consider this a hard process given it takes over 25 hours, but it definitely was the most fun interview I have had. During the hackathon, we were given a mentor in the beginning of the night to make sure everything starts smoothly. After the mentor left for the night, the SMEs were available to help until 3 in the morning. From 3-8am there were no people on duty. Around 9 o'clock, another mentor comes around and gives a small interview.

Technical interview with Hackerrank after submitting initial application, two different problems, both very reasonable in the given timeframe. Sadly did not get an offer, nor any feedback at this stage.
