I applied through other source. The process took 3 weeks. I interviewed at Viridien
Interview
The first interview was a few simple math questions over the phone. The second interview was in person and involved a normal interview, followed by more problem solving questions. They took me out for lunch afterwards.
Interview questions [1]
Question 1
6 Horses are racing around a track. They all start at the starting line and at the same time, and run forever. Horse 1 takes 1 minutes to finish a lap, horse 2 takes 2 minutes to finish a lap, etc.
Aside from the starting point, when is the next time 4 horses are at the starting line at the same time?
I'm pretty sure this was how it was worded.
There were two interviews, one with HR and another with two people from the technical team. Interviews happen back to back on the same day. Interviewers were friendly and chatty, didn't pressure when you were trying to solve the problem, and explained how to get the solution if you didn't get it.

Question 1
HR - just general questions about yourself
Technical - Some maths/iq question plus basic questions about seismic processing
The first is a phone interview with three math questions. They may also ask you when can you start to work. These math questions will not be hard for you if prepare yourself well through the Glassdoor.
