I applied through LinkedIn for a position in Berlin. All the interviewers and HR were super nice and friendly throughout the interview process.

First, there was an HR call, which was followed by a Coding Assessment. You have 3 hours to GET data from an API, process it, and send it back via a POST API. I personally found this coding assessment very good and practical compared to other companies' patterns, such as using platforms like Codility or giving projects to complete over a week. It also shows the effort the company puts into hiring candidates.

The coding assessment was followed by 4 interviews over the course of two days:

1. Coding + Behavioral Interview [1h] a. Merge sorted lists and cut to length k. b. Find the most common substring in a string of length k.

2. System Design + Behavioral Interview [1h] Design Tiny URL.

3. System Design + Behavioral Interview [1h] Add weather for customers on the HubSpot platform.

4. Behavioral Interview [45 min]

After all the interviews, the decision usually takes one week. However, in my case, the Engineering Manager of the team I was supposed to join was on vacation. Once he returned, I had a 30-minute call with the EM. It was a casual chat about my interests/motivations and a platform for me to ask anything about the company.

Some Behavioural Questions:

1. Tell me a time when you made a mistake and how you corrected it.
2. Tell me a time when you had a conflict with a colleague and how did you handle it.
3. Tell me about a time when you took ownership.
4. Why are you leaving your current company?
5. Tell me about any side project you have worked on.
