Screening call with a recruiter follow by a technical interview.
The question was the same paint question that others have posted about. The interview seemed to go well, and I solved the problem, and all of the interviewer's test cases. However, I received a rejection e-mail a few hours later.
Overall, seemed to be a waste of time. Seems odd to have just one person be the gate-keeper instead of having a hiring panel like most companies.

Question 1
Create a Painter class. The same question that others have posted about.
I applied online. The process took 2 weeks. I interviewed at Color (Burlingame, CA)
Interview
The process consisted of 2 coding interviews, 1 system design interview, and 1 behavioral interview with manager. The interviewers were all friendly and patient. We didn't even compile the code I wrote, we just talked through it.

Question 1
Rest APIs, basic coding (any language was fine), OOP patterns
The interview process started with an informal HR call and then a phone screen. The phone screen was scheduled with a senior engineer but instead someone else joined in with no clue on how to interview. I was not given time for introduction and the interview jumped right into the coding question. They were using Codility platform and I was unfamiliar with the platform. The link to the shared pad was given on the spot so I had no time to get comfortable with the platform. The interviewer offered NO HELP whatsoever even when I explicitly asked "How do I run this?" They said - I'm not sure. So I had to spend time figuring it out by myself and after going through my code and testing it, they mentioned a use case that I missed for which I had to restructure my entire code. I kept asking if I was going in the right direction but no helpful response or hints. The interviewer was just staring at me the whole time.
At the end of the call, I got to know that the interviewer has been been in the company for 6 months so I got no insight whatsoever into the company culture, the team responsibilities, etc.
Overall a very bad experience, I won't be engaging with this company again.
