I applied online. I interviewed at Viridien (Houston, TX) in Sept 2017
Interview
3 math questions, and you need to answer the questions, there is no limit of time of answer the questions but I guess the faster the better. I take about 30 mins to answer the whole questions, it is not so difficult.
Interview questions [1]
Question 1
if you drive 35 mph, you will late for 1 hour. 50 mph ahead for 0.5 hour. How far is it?
First round is phone interview, a manager called and asked me when can I start work and then 3 math questions. Not very hard if you prepared well. Signal is not very good.
I applied online. The process took 2 months. I interviewed at Viridien (Houston, TX)
Interview
2 phone interviews, one was about 3 math questions. The second phone interview was about my work and also another set of math questions. After the second math interview I was offered an onsite interview.
