Three interviews were conducted.

Since I was applying from a different country for the job position, all of them were via Skype or phone. The first interview was conducted via phone and was completely technical.

Next, I was asked to go to SAP offices in the country I love for a Skype interview. The reason for this was unclear.

There was an additional Skype interview. Both of these interviews were completely technical.

The first two interviews were directly with the engineering manager. The last one included two other team leaders.

Two weeks later, due to no answer from SAP, I called HR. Three days passed, and I received a very generic email announcing the end of the process.

All the interviews took around 4 months.
