It is an open interview. The interview conducted by HR so the question not hard but tricky. Overall experience it was a good interview. Need to be fully prepared with the job scope for the position you apply

Everything was online / via phone. Glassdoor wouldn't give me the option to say that, so I wrote my college location instead. I got a call from a recruiter three weeks before graduation. She has seen my profile on LinkedIn or Career Builder. She told me about Schlumberger (SLB), asked me some behavioral questions. Then about a week later, I got sent interview information for the following week. The interview was two parts: (1) presentation by recruiting engineers over zoom, to 50 potential candidates (2) about five hours later, an individual 30-minute interview between me and 2 recruiting engineers. I had to present a powerpoint presentation about myself, why I believe I would be good for the job (school, past experiences (projects, internships, leadership)), and what I wanted to get out of it. They asked me some behavioral questions (like 2 or 3) and that was it 2 weeks after this I got a text from the recruiter that they would be offering me employment. I had to wait about another three weeks (it was over Christmas break) for the official letter since it was coming from overseas (They gave me an international posting, even though I didn't specifically apply to international jobs. The job requisition I was sent by the recruiter didn't mention a location, but I campaigned to be sent overseas during my interview and it worked haha).
