Scewo interview questions

The first interview was a friendly phone conversation directly with the team leader of the job itself. The second interview was with the team leader and another team member and was technically focused - very easy questions. The third interview was held in person in Winterthur. During this final step, after some initial presentation of the team and the equiptemn in use, I was asked to dig into their code, understand it and perform a code correction. I was stunned that they were expecting me to understand in a few hours on my own the system and perform the bug update even though they offered me one team member to support my actions. The task was not clear that I have to perform this activity on my own taking into consideration the provided entity for help. Finally, I had to prepare a presentation on site about an IMU sensor and present it in front of the team.
