I applied through college or university. The process took 2 weeks. I interviewed at SLB (Houston, TX) in Oct 2019
Interview
I applied online and then got invited to an on-campus interview a few days later. The interviewer asked me about my experience and some conceptual questions about math and statistics. He was friendly but he was a software engineer and I was applying for the data scientist position. The next day I got an invitation to do a skills assessment on HackerRank, which I completed within a week. It's been months and I haven't heard anything since. I even emailed my recruiter twice and never got a response. I think if a candidate takes the time to interview for a position and to complete an assessment, they at least deserve to hear back about their application.
