Candidate interview experiences
First-hand accounts from people who interviewed at the LEGO Group.
Senior Software Engineer
The whole thing took about 6 weeks. It started with a nice chat with HR, then a coding session where I paired with a senior engineer. After that, I talked to a director, then had a panel interview with some lead engineers. The final step was a presentation to a director about a small project they assigned. Everyone I met was great – really professional and clear about what they expected. It was a tough process, definitely harder than average, and took a lot of time. I didn't get an offer in the end, but it was a solid, respectful experience. It's a big time commitment, which might be tough if you're already swamped at work or need a job fast. It would have been easier if they'd given clearer info upfront about how much time it would take or maybe combined a couple of the rounds.
- Can you tell me about any code analysis or static analysis tools you've used specifically for embedded software?
Software Engineer
The whole hiring thing took about 3 months and had a few interviews. First was an online one where I had to record myself answering general questions about me. Then came an assessment day for everyone, split into groups. Before that, we got a small code repository to check out and figure out what to improve or change. We talked about this in groups with others, watched by the hiring folks. After that, there was a short time to chat with the hiring team and other candidates. The final interview was more standard, just me and two LEGO people. It was mostly about getting to know me and how I solve problems, with high-level tech questions.
- How does the LEGO group align better with your career goals compared to your prior workplace?
Software Engineer
My initial chat with the recruiter gave me a good idea of the overall interview steps, and my meeting with the manager felt pretty relaxed. Some questions I hadn't really prepared for, and I was worried I wouldn't be able to express my thoughts and opinions well enough to show I'd be a good colleague and person. The technical interview, which included a case study, was definitely the toughest part – it's been a while since I had to dive into so many new concepts so fast, but it paid off and I felt like I did well. I was also comfortable during the interview (which was in English, not my native language) and had enough time to cover what I needed to.
- Can you share your contributions to fostering inclusivity at work?
