Process

I applied through a recruiter. The process took 2 weeks.

1 recruiter interview
1 take-home technical test, a bit long (a full week of work) but they want to rework it to make it shorter in the future
1 technical test feedback interview with 2 developers (20 min product presentation, 20 min technical presentation), be prepared with questions even though there isn't always enough time left to ask them
1 interview with an EM, more situational questions, more time to ask questions
Response within 2-3 days

Questions

Technical test:

Why did you use act in the tests with react-testing-library
How did you organize your code and why that way
What product / technical improvements could you make

Situational interview:

Can you talk about a difficult communication situation you experienced
Can you talk about a project you worked on and were proud of, and why were you proud of it

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.
