I applied in-person. The process took 5 weeks. I interviewed at SLB (Houston, TX) in Oct 2023
Interview
Got a Karat interview invitation after talking to a recruiter at a career fair, with 3 space/time complexity questions and 3 coding questions. After completing it (finished 2/3 of the coding problem), got an email inviting me to a 2-day onsite in Houston, TX. The first day is dinner and networking. The second day is the onsite interview (morning or afternoon). You would have to give a 7-minute presentation along with other applicants (they do it in 5-person groups), then 2 rounds of 45-minute technical interviews and 1 round of HackerRank. Results will be out 2-4 weeks, I haven't heard back yet.

Question 1
For the onsite technical interviews, they ask different questions depending on what software role you are applying to (frontend, backend, full stack, etc.) How would you design a library system, with the functions of adding, deleting, and modifying users and books?

Interview
There was a phone screen with the hiring manager that was mostly behavioral. The next round was an on site with 4 people (all engineers) and a group interview to end the day.

Interview
I applied online; the interview was conducted by Karat Studio, which was a third party conducting technical interviews for SLB. The interviewer was quite friendly and explained the process pretty well.
Interview questions [2]
Question 1
Asked three complexity and data structure application questions,
Graph-based LeetCode-style question, another follow-up with slightly higher difficulty. Be prepared to define classes/methods and run your own test cases.
