I had one initial video call where we talked in general about Spotify and software.

They decided to continue with me and booked a "technical screening," which was another video call with two programmers. They asked me to type some code for very basic problems, such as reversing a vector, reversing words in a sentence, and printing the Fibonacci sequence.

After this, we booked a lunch and three meetings with the team. They wanted me to solve problems like designing a "disk cache," perform pattern matching, and reduce sentences.

I solved everything without any issues but was later evaluated as too unstructured and did not get the job.

Reverse a vector. Reverse words in a sentence. Print Fibonacci efficiently. Talk about complexities. Design a disk cache. Remove duplicated sentences from a list. Etc.
