Across the three IBM Data Engineer reports, the common thread is that interviewers lean on your own project work more than on pure algorithm drills. One candidate described a fast, direct technical interview tied to past work and personal responsibilities. Another was asked detailed questions about the data platforms they had used. A third was asked about the services in their toolset and how they handled a challenging project. Be ready to say exactly what you built, not just what the team did.
Topics differed by candidate. One report covered warehouse versus data lake trade-offs, Spark architecture and lazy evaluation, SQL, a basic Python string reversal, generative AI questions, and a maximum-length bitonic subarray problem. Another covered governance in the systems they built, scenario-based SQL, data modeling, and ETL and reporting, and noted that PySpark debugging can come up for Spark-aligned roles. The difficulty ranged from basic to uneven, with the bitonic problem the one clearly algorithmic item.
One candidate described a manager round that was less technical and included salary, which the team settled later. Another mentioned a managerial component where compensation could be negotiated. Either way, have a salary expectation ready.
Two candidates accepted offers and one reported no offer. One of them described scheduling problems, including a missed interviewer and a cancelled final round, in a business unit recently acquired by IBM. With only three reports, expect the format to vary by team and interviewer.

Synthesized from candidate reports. Individual experiences may vary.
One candidate reports starting with an introduction to their background before the conversation moved into projects. Expect to summarize your experience concisely, then be ready for follow-up on the data platforms and responsibilities behind each resume item.
Candidates report a technical round anchored in their own projects. Topics reported include warehouses versus data lakes, Spark architecture and lazy evaluation, scenario-based SQL, data modeling, governance and basic Python, and one report notes PySpark debugging can come up for Spark-aligned roles. One candidate also reported a bitonic subarray problem. Difficulty was described as basic to somewhat difficult.
One candidate describes a manager round that was less technical, covering the role, responsibilities and experience, with salary discussed and the amount shared by the team later. Another mentions a managerial component where compensation could be negotiated. Prepare a salary expectation and examples of how you keep learning new tools.
One candidate lists a PDMr round after the technical stage. Another says an HR stage is standard after the managerial discussion, but their final round was cancelled when an offer arrived. Final steps appear to differ by team, and scheduling problems were reported once, so confirm each appointment in writing.
