I applied through college or university. The process took 2 months. I interviewed at Datatron (Palo Alto, CA) in Nov 2019
Interview
Went through one round of phone interviews, followed by two rounds of coding assessment. Interviewers were really interested in your background, and technical skillsets. Friendly interview process and serious during the coding assessment.
I applied through college or university. I interviewed at Datatron in Nov 2016
Interview
It was a very technical interview. Preparation was definitely needed to be able to meet the expectations for the interview. I was given medium difficulty coding questions and was able to do fine.
The interviewers are definitely looking out for strong thinking skills and a good approach to solving a problem. Some computer science foundation knowledge would also be expected.
