Data Engineer Interview Experience

Process

I applied online. The process took 2 weeks.

There were 3 interviews out of 4. The first two went very well. The 3rd one with the Data Lead went very well too, except that the feedback was negative without really understanding the reasons. Having answered all the questions, I didn't have any feeling of uncertainty. I have taken many interviews in my life, and I know when there are ones where it goes badly.

Pros: Company culture is fantastic. Founders come from Booking and they try to apply Booking culture and values @ Pennylane. That created a special treat for employees. You're really appreciated and respected in each way. Good work life balance. No overtime if you don't really insist :) A chance to work with really good people and learn from senior engineers a lot. Gatherings at Paris 5-6 times per year They treat remote people the same as employees from France.

Cons: Tech staff grew from 50 to 100 people in 2022 so now the product is quite huge and there are a lot of new people, but this can always be an advantage since it offers learning opportunities.

Good days off, but terrible management and stress

Senior Software Engineer • Former Employee

October 4, 2026

Pros: Proper amount of days off Good people on the team trying to help with PM on the top.

Cons: haven’t seen such a terrible way of managing people and teams in my entire career — from senior leadership down to the Engineering Manager level. During my time there: I saw people constantly getting sick due to stress. Employees were indirectly expected to work overtime and were compared to those who did. There was constant turnover and frequent changes of Product Managers and Engineering Managers, which created instability and a lack of clear direction. The management culture created a lot of unnecessary pressure and unhealthy competition. Ah, I almost forgot! Micromanagement — the cherry on top. It was funny to see that the EM kept chasing people and nitpicking instead of figuring out how to improve features and helping with technical decisions. If you are experienced and have a family, I would not recommend joining.
