I applied online. The process took 4 weeks. I interviewed at Hopper (Singapur) in Nov 2022
Interview
Initial round went ok, Hopper is hiring in Asia because the Asian travel market requires different features. Their tech stack is mostly Scala after their migrated their Python and Golang services over.
Interview with hiring manager showed that the particular team (APAC flights) was basically empty of engineers. The hiring manager joined 6 months prior and 2 engineers resigned plus one engineer was let go during this time. I wouldn't call this an instant red flag, but it's definitely something to look out for.
For the tech screening, even as a senior engineer you're still expected to do basic LeetCode/Hackerrank questions. The interview is conducted in the hackerrank IDE which defaults to Python.

Good thing I didn't waste my time on it.

Don't bother. Just like previous reviews, they're using cases to procure free ideas for their app. Also, take a look on LinkedIn at those who hold a product management position at the company. If you don't look like that, chances are you're not getting i.
