SLB Intern interview questions

I applied on campus so First there was a Coding round which was followed by tech interview and a hr round. The interview was online and the interviewer asked several questions on OOPS Data structure and ML and AI

You will need to pass 2 interviews. A recruiter gave me call on random day and time, I was quite in shock but managed to pass that first step. Another interview is from panelists. Sadly, I had to reject the 2nd interview due to personal matter. Hence, I did not finish the whole process.
