First-hand accounts from people who interviewed at Qt Group.
Marketing
The hiring process lacked clarity on the timeline and steps involved. There were significant delays of two to three weeks between communication. After almost two months, I was notified that hiring was halted for the upcoming year. Better planning and a more structured approach from the beginning could have prevented this. For a role that isn't technical, it's surprising the process lasted longer than a month. I would have appreciated more transparency regarding the reasons, such as a hiring freeze or budget constraints. It was quite disheartening given my long-standing admiration for the organization and my strong desire to join.

Sales
The initial part of the interview process was okay, but the way they handled the last step was really bad. I first had a screening with the Talent Acquisition people, who were great and easy to talk to. Then I had a first interview with the Hiring Manager, which was pretty standard. After that, I was set up for a final interview with the Sales Director. But then, the night before, they called it off because they decided to close the job opening. This was totally their call, not about me. I'd already put in a lot of time getting ready for that last interview. Cancelling so late for reasons they could control shows they don't really respect candidates' time. If they were in a hurry to hire someone, they could have said so and maybe moved things up. Instead, they just cancelled without thinking about me. Even though this is just one thing, I think it shows what kind of company this is. Honestly, I'm glad I'm not moving forward with a place that treats people like this.

Software Engineer
I had a hiring manager interview which was a mix of behavioural and technical questions. Then, there was a technical interview with two interviewers that involved a pair coding exercise and some technical questions. After about two weeks, the hiring manager told me they decided to hire someone with more experience.
- Questions regarding C++
- Questions about memory
- Questions about debugging
Senior Software Developer
I applied online and filled out the application form, which had basic info and a salary expectations question. After a month, HR emailed me. There were 3 stages: 1) HR screening with questions about me, my experience, current role, and salary expectations again. A few days later, I got invited to a technical interview. 2) The technical interview was a simple LeetCode task I solved in 10-15 min with the best complexity and answered a few C++ questions based on my code. It was scheduled for an hour, but I finished in 30 min. The interviewers seemed friendly. I got positive feedback and an invitation to the 'on-site' interview. The 'on-site' interview was 4-5 hours at the Qt office in Adlershof, with 4-5 parts: 1) Another technical coding interview (fixing bugs in a Qt framework app, 1 hour). 2) Another technical theoretical interview. 3) Lunch with the team. 4) Behavioral interview with HR and my manager. 5) A short presentation on a technical topic or my experience (optional, I skipped it). I fixed the Qt app, passed the theoretical part, but during the behavioral interview, they asked about my salary expectations again and if I was ready to negotiate. This was strange since I'd already passed all technical parts and my salary expectations were known from the application.
