Looking for ML roles in Europe took longer and was more draining than I'd expected. I sent out 32 applications over roughly three months, and the pattern of rejections got predictable fast: most teams either wanted a PhD as a hard filter or were exclusively chasing LLM fine-tuning experience. My background is recommender systems and production ML tooling, the unglamorous plumbing that keeps models running at scale, and that combination landed awkwardly in a lot of job descriptions written with transformer research in mind. I got through to interviews at six places total, which felt like a low conversion rate for the volume I was pushing, and a couple of those early rounds ended with feedback that basically confirmed I was the wrong shape for what they were building.
The offer I eventually accepted came through a referral, and that was the only thing that broke the pattern. An ex-colleague from a previous startup had joined Zalando in Berlin and flagged my name internally when a Senior ML Engineer position opened up. That internal signal seemed to get my application read differently. The recruiter reached out within a week, which hadn't happened anywhere else in this search. The process itself was rigorous: three technical rounds covering system design, coding, and a deep dive into my recsys work in production, plus a separate interview that genuinely surprised me. They called it a paper-discussion round. The format was that I had to argue both sides of a recent ML paper, switching positions mid-conversation when the interviewer pushed back. It was uncomfortable in a way I respected. They wanted to see how I thought, not just what I'd memorized.
The offer came in at 95,000 EUR for a full-time, on-site role in Berlin. The base is below what comparable US roles pay, and I knew that going in, but the package included 30 days PTO and full visa support, which made the real-world math work for my situation. Ninety-one days after I started applying, I accepted.
Two weeks. Three rounds. One offer. The fastest hire I've ever been involved in, on either side of the table.
I wasn't job-hunting. I'd been at my previous company for two years as the second DevOps hire. I liked the team. The infrastructure was a mess, but a manageable mess, and I'd been making it less of one every quarter.
A former colleague, someone I'd worked with five years earlier at a very different company, had moved to a Dublin cloud company eight months prior as the engineering manager for the platform team. We'd stayed loosely in touch. On a Monday morning in late autumn he pinged me on Slack: "we're hiring a senior DevOps person for my team, you'd be perfect for it, can we talk?"
I said yes mostly out of curiosity. I had no plans to leave, but I was happy to hear what they were doing.
The first call was him, forty-five minutes. No formal recruiter screen. He walked me through the team, the stack, the on-call rotation, the salary band, the team's biggest current pain (a Kubernetes upgrade that had been deferred for six months), and what they hoped to ship next quarter. By the end I had a clearer picture of the role than I'd had of any role I'd interviewed for in the previous year.
Round two was the head of platform and one other senior engineer. Sixty minutes, structured as an "infrastructure design" conversation. They presented a real problem they were working through, how to handle blue-green deployment for a stateful service with a managed database, and asked me to think out loud. I'd thought about variants of it before. We disagreed on one specific point about traffic shifting, and the conversation got more interesting there.
Round three was an "incident response" round with two engineers. They walked me through a real outage from two months earlier, slowly, runbooks open, and asked what I'd have done at each decision point. There were a few places I'd have gone differently. I said so. They were pleasant about it.
The final round was twenty minutes with the CTO. He asked two real questions: what would make me leave a company, and what would make me leave this one specifically. I told him.
The offer arrived the next morning. €82,000 base. Same as their advertised band, no negotiation needed, because they'd told me the band on the first call and asked specifically whether it worked for me. I'd said yes then. I said yes again now.
The whole process, from first Slack message to signed offer, was fourteen days. It worked because every round was someone who'd actually read about me, had a clear question they wanted answered, and respected my time. The recruiter screen never happened. No take-home. No gimmicks. It was the best interview process I've ever been through, and I think the only reason it worked was that an internal person was vouching for me from minute one.
