I applied online. The process took 4 weeks. I interviewed at SLB (Houston, TX) in Nov 2018
Interview
On campus behavioral --> coding challenge --> superday with 4 interviews and 1 presentation.
It was absolutely garbage. First, the recruited emailed me literally the DAY BEFORE the superday seeing if I was able to come. Anyway, I was pretty happy that I called into the superday. I thought I did relatively well because one of the four interviews (coding challenge), I solved it so fast that they had to give me another. The behaviorals went relatively well as well.
The worst part was after the interview. The recruited told us she would get back to us within 2 weeks. Well, after ~4 weeks, I emailed her because I had not received anything from Schlumberger. No response. I ended up going into the website and finding out I was rejected there (though this appeared after I emailed her; before the email, it said pending). Unprofessional recruited, unpleasant experience, overall a waste of time.
