I applied online. The process took 3 weeks. I interviewed at Lucid Software (Salt Lake City, UT) in Nov 2018
Interview
1. Machine Learning take-home assignment that had to be completed in 3-4 days. Recruiter advised completing in about 4 hours. However, it took me about 10 hours to solve it since the data size was huge!
2. Machine Learning / Case Study Interview - Conceptual ML case study questions and some questions from the previous take-home interview.
3. Business / Case Study Interview - A mix of behavioral and business case study questions. Required good communication skills, logical reasoning, and business acumen.

Interview
I applied online and was very quickly sent a take-home challenge. I took about 8 hours to finish and I got chance to chat with hiring manager. The questions were standard, but the problem was that they were looking for immediate hires, a criteria that I clearly didn't satisfy from my resume (as I am still a current student and I list my expected graduation date, which is far away from the time I interviewed). I wouldn't have wasted the time if I had known this earlier.
