Our candidates report that PwC’s ML Engineer interviews are less about trick questions and more about whether you can stand behind every line on your resume. The strongest signal is ownership: interviewers keep pressing on what you personally built, why you chose a given method, and what changed because of your work. In one experience, the conversation stayed tightly anchored to AI projects from the CV, with repeated follow-ups on methodology, implementation details, and measurable outcomes. That tells us PwC is looking for engineers who can translate applied ML work into a clear, defensible narrative, not just name-drop models or tools.
A recurring theme is the emphasis on applied depth in areas like computer vision, image processing, graph knowledge databases, and LLMs. We’ve seen candidates asked to unpack work on the Cell Painting dataset, explain image processing algorithms they developed, and discuss specific neural network families such as CNNs, RNNs, and GANs. The non-obvious part is that the bar is not just technical breadth; it’s whether you can connect the technical choices to the business or research result without drifting into vague summaries. PwC seems to reward candidates who can speak precisely about method, contribution, and impact while keeping the explanation conversational and grounded.

The first round was a technical interview that leaned much more on my CV than on puzzle-style questions. It was structured, but the interviewer kept it conversational and spent a lot of time digging into the AI projects I had listed on my resume. They wanted specifics on what I personally owned, what methods I used, and what the results were, so I had to walk through my past work in detail rather than just give high-level summaries.
A lot of the discussion centered on image processing and applied ML/DL work. I was asked to explain the image processing algorithms I developed, how I used machine learning and deep learning models, and what my experience was with graph knowledge databases. They also asked about my contribution to the Cell Painting dataset and how I had used large language models in my work. One of the more direct questions was what types of neural networks I had worked with, including CNNs, RNNs, and GANs. The overall vibe was friendly, but it was clear they were evaluating both technical depth and how well I could communicate complex work clearly. I ended up receiving the offer. My main takeaway is to be ready to defend every bullet on your resume and to explain your projects at the level of methodology, implementation, and outcome, especially if your background includes LLMs, computer vision, or graph-based work.
Prep tip from this candidate
Be ready to go line by line through your resume projects, especially any image processing, Cell Painting, graph knowledge database, and LLM work. Practice explaining exactly which neural network types you used and why, since they asked directly about CNNs, RNNs, and GANs.

Synthesized from candidate reports. Individual experiences may vary.
The first round was a structured but conversational technical interview that focused heavily on the candidate’s CV and prior projects rather than puzzle-style questions. The interviewer dug into specific AI/ML work on the resume, asking what the candidate personally owned, which methods were used, and what results were achieved.
This stage centered on applied machine learning and deep learning experience, especially image processing, computer vision, and graph knowledge databases. The interviewer asked detailed questions about algorithms developed, use of ML/DL models, contributions to the Cell Painting dataset, and experience with large language models and neural network types such as CNNs, RNNs, and GANs.
The process concluded with an offer decision after the technical evaluation. Based on the experience shared, the interviewers were assessing both technical depth and the ability to clearly explain complex work, and the candidate ultimately received and accepted an offer.
