Medium hard. Will need to be fit very well with the job requirement. Both recruiter and hiring manager are very nice people. Hiring manager asked about technical background and working expertise.
I applied online. The process took 5 days. I interviewed at Tesla (Aachen) in May 2022
Interview
Instead of getting asked usual questions, I got three scientific papers to read and had 6 hours time to answer a multiple choice test. This was very stupid and did not fir with the things i applied for. They "just" gave me the test. Everything in english even though I applied for mechanical design internship at Tesla germany.
