Candidate interview experiences
First-hand accounts from people who interviewed at Trafilea.
Senior Frontend Developer
There was an HR interview and then a technical interview. They asked general front-end questions, followed by two live coding exercises. If they don't like you, they just ghost you without feedback, so don't waste your time because they don't respect candidates.
- What improvements would you suggest for this code?
Senior Frontend Developer
I was contacted on LinkedIn and the selection process was quite extensive, spanning about 1 to 2 months. It started with an initial chat with HR. Then, I had to do two behavior tests (Kolbe and another I don't recall) and a Wonderlic test. After that, I received a technical challenge on Hackerrank, which had technical questions, a code review part, and a coding implementation, taking about 2.5 hours. This was followed by a technical interview with two interviewers, where they asked questions and gave me problems to solve. Next, I had to fill out a long form with personal details and work references. Then came a nearly 2-hour meeting with HR, called the "Tandem Interview". I understand you have to "pass" each stage to move to the next. Throughout, I got positive feedback, so I was looking forward to the final decision. But recently, they told me they decided not to make an offer because the CEO preferred candidates with specific e-commerce project experience. My issue is that this seemed crucial and was clear from my CV from the start. I think the process could have been smoother by checking these essential requirements early on to avoid wasting so much time for everyone.
- Tell me about the Hackerrank test.
- Technical interview with questions and answers about basic and advanced JavaScript and React concepts.
- Explain the event loop.
Front End Developer
It was a video call interview with three rounds. The first round was just an intro, the second was a bit technical, and the third was more about how I'd handle different situations. The interviewers were nice and the whole experience was good.
- Tell me about a past project where you disliked your approach.
