I applied through college or university. The process took 3 weeks. I interviewed at SLB in Oct 2022
Interview
you first get phone interview with a third party company and if you pass that, you get scheduled for an onsite interview where they fly you to their office in Houston. on the first day you have a networking event with the other candidates and the hiring managers. On the second day you give a presentation about a project you worked on and then get 3 rounds of technical interviews. The whole process was horrible starting from the recruiter that gives vague answers and is passive aggressive when you ask questions to one of the interviewers that wasn't prepared at all and was making up questions that weren't for an entry level position. They also claimed they will reimburse travel expenses which never happened (5 months later). Finally they just ghosted me after the onsite even after emailing them. They will probably never reply to your emails or reimburse your expenses unless you received an offer. Do not waste your time here.
