SLB Full Stack Engineer interview: puzzle, project discussion, DSA, and design

My process opened with a general HR-style introduction and then moved into technical rounds. The first technical round was light, with a basic puzzle that felt more like a check on how I think than a demand for deep mastery. A project discussion followed and became a standard conversation about explaining my work clearly.

The next technical round shifted to medium-level DSA with basic system design. It felt balanced: data structures and coding alongside high-level architectural reasoning. I spoke with several engineers, and the overall experience was structured without feeling hostile.

The difficulty increased in a clear order: easy puzzle, project discussion, then DSA and system design. I came away feeling I could handle the fundamentals, but the rounds still required solid reasoning rather than buzzwords.

Location: Roorkee. Overall feedback: Positive. Offer status: Got offer.
