Spotify Backend Engineer interview questions

system design is super super hard, others are easy, I am super frustrated about this question, its a mid level question and I feel really hard to deal with... wish all of you good luck!

I had 3 rounds: 1. Phone screening with hiring manager: my background, feedback culture. Fairly standard. 2. Technical screening with 2 engineers: tell in depth about one of my recent projects, general technical questions (TCP/UPD, DNS, etc). One easy LeetCode problem. 3. 4 interviews on last stage: values, algo & ds, system design, case study. Values - normal set of values/behavioral questions that should be answered with STAR. Algo & DS - 1 medium LeetCode problem. System Design - basic system design task, not complex system. Case study - debug previously occurred production incident. Interview process was good, hiring manager kept me updated during whole process and helped a lot. Interviewers were great and friendly, I did not feel like it was "gotcha" type of interviews, but rather they genuinely tried to know more about me. My advice: clearly explain and speak aloud your thought process on technical interviews, and prepare STAR format answers for most commonly asked values questions in advance and memorize your answers.
