The two KLA machine learning interview reports we have both center on discussing your own work in detail. One candidate, interviewing for a machine learning and computer vision internship, had a first-round hour split into three parts: a discussion of their publications, scenario-style deep learning questions, and a LeetCode-style coding problem. They were asked to explain the models and design choices behind their papers, not just summarize them. They were told a second round would follow the next week but were rejected after the first.
The other candidate, interviewing for a Machine Learning Engineer role, began with a take-home Python exam they described as relatively straightforward. They were then invited on-site, where they presented a research project to a room of interviewers and held back-to-back one-on-ones. Those sessions focused on projects listed on their resume, including their approach and technical decisions. They found the questions somewhat surface-level and felt one interviewer was more interested in picking apart their explanations than in a constructive dialogue. They did not receive an offer.
The two reports describe different formats, so don't treat either as a fixed template. A sensible way to prepare is to put together a concise walkthrough of your strongest project, covering the motivation, model choices, trade-offs, and results, and to practice answering follow-ups about it. Keep standard coding practice in your routine in case a live problem appears. If a conversation turns tense, asking clarifying questions can help keep it collaborative.

I started with a take-home coding exam as the first round, which gave me time to think through the problem without real-time pressure. It was relatively straightforward Python work, nothing overly complex algorithmically. Once I passed that, I was invited on-site for the full loop.
The on-site day began with a presentation where I walked through one of my research projects in front of all the interviewers. It was a full room, which definitely added some pressure, but it was nice to have everyone aligned on my background upfront. After that, I had back-to-back one-on-one sessions. Each interviewer dug into my past projects listed on my resume, asking clarifying questions about the work I'd done, my approach, and the technical decisions I made. The conversations felt somewhat surface-level—they weren't drilling deep into novel research directions or asking me to solve new problems on the fly. Instead, it was more about understanding what I'd actually built and why.
I also got an office tour and had a chance to chat with some team members, which gave me a sense of the environment. On paper, it seemed like a great place to work. But during the interviews themselves, I found the dynamic a bit cold. One interviewer in particular seemed more interested in picking apart my explanations than having a constructive dialogue, which made the experience feel less collaborative than I'd hoped. In the end, I didn't receive an offer, and in hindsight, I wish I'd pushed back more on those tense moments or asked more questions to understand what they were really looking for.
Prep tip from this candidate
Be ready to present a research or past project to a group and then discuss it deeply in one-on-ones—practice articulating your technical decisions and impact clearly. Also, manage the dynamic: if an interviewer seems adversarial, ask clarifying questions that reframe the conversation as collaborative problem-solving rather than a defense.

Synthesized from candidate reports. Individual experiences may vary.
One candidate, interviewing for a Machine Learning Engineer role, says the process began with a take-home coding exam. They describe it as relatively straightforward Python work without complicated algorithms, and passing it led to an invitation for an on-site interview.
The internship candidate says the interviewer opened by explaining the format of the hour, which had three parts. The first covered the candidate's publications, and they had to walk through the models and design choices behind their work rather than give a high-level summary.
In the same internship interview, the publication discussion was followed by conversational, scenario-based deep learning questions about approaching ML problems in practice. The hour ended with a LeetCode-style coding problem, and the candidate felt reasoning under time pressure mattered as much as speed.
The Machine Learning Engineer candidate reports that the on-site day opened with a presentation of one of their research projects to all of the interviewers. It was a full room, which added pressure, but it gave everyone the same background before the individual sessions.
After the presentation, the Machine Learning Engineer candidate had back-to-back one-on-ones centered on projects on their resume, with questions about their approach and technical decisions. They also toured the office and met team members, and did not receive an offer. The internship candidate was rejected after the first round.
