I applied in-person. The process took 3 days. I interviewed at SPAR (Maastricht) in Jun 2021
Interview
Very quick, asked mostly what my student status was and I was allowed to start the next week. It was one on one, and they were quite polite towards me.
Firstly they sift all the applications, then they choose the ones they like and invite you for an interview. They tell you where it is and what time to get there so I did a trial run just in case.
First call was highly helpful, leading to a comprehensive interview where key points were discussed, duties developed and explained, and collaborative decisions made, Really nice and good process. word word word
