I applied through an employee referral. The process took 3 weeks. I interviewed at Viridien (Houston, TX) in Apr 2018
Interview
Referred by an employee, scheduled an initial phone screen after less than two weeks, informed pass the initial phone screen next morning and scheduled second one, now waiting for second phone interview which I choose to be on April 30th. They ask 2-3 math questions which are high school level, just calm down and make sure you have enough paper to calculate them clearly so that you can explain your procedure to interviewer.
