I applied online on Spotify's website and within a week received a call from a recruiter. After reviewing my CV, the recruiter said an engineer would contact me for a Skype interview.

The Skype interview was held one week later. I was asked rapid-fire questions from almost all the computer science courses I had taken in my bachelor's, such as data structures, OS, databases, and algorithms.

One week later, I had another Skype interview. My programming skills were tested, and I had to write code for 4-5 problems on a shared editor.

A week after that, the recruiter informed me I would soon be called for an on-site interview. Thanks to their poor management, it took them a month before I was actually called.

Anyway, the on-site interview was four hours long, with one system design interview, two programming interviews, and one culture interview (which included lunch with their team).

The very next day, the recruiter told me they were looking for a mentor for me since I was a new graduate.

Two weeks after that, the recruiter said they had found a mentor and that she would finalize all the details and paperwork and get back to me.

After that, it took the recruiter a month before she finally got back with an answer. She said the position I had been interviewing for had been merged with another position due to organizational changes and that she would contact me again if she found another suitable position.

Since then, I am waiting for her to contact me. The whole interview process was filled with lengthy delays and spanned a total of three months!

Although I have all the questions from all interview stages documented in a Word file, I am not sure if I am allowed to reveal them here. However, to give you a hint, I will paste only a few questions here:

Interview 1:

• how does traceroute work?
• difference between Big Endian and Little Endian (with example)?
• BSD vs GPL vs LGPL vs FSF vs GNU?
• 255 & 42 = ? (solve in 15 sec)
• 11 << 2 = ? (solve in 15 sec)
• what is TTL in a packet?
• give examples of functional programming languages
• what other language runs on JVM?

Interview 2:

• write code for the Fibonacci series. Later, improve it.

On-site Interview:

• (cannot disclose)
