This is a story from a few years ago, but I figured you guys might like it. It was big lesson for me.
I was just starting to work as a young adult, looking for a part-time job related to my field of study. I found the summer guide job at the castle which looked interesting, so I sent out the CV and then ended up being invited for the interview.
It was rather complicated to get there. The castle was at the other end of the country, “only” two train rides away. My interview was scheduled for one cold day in January. As a bonus, I also had an injured foot at the time and was limping, although I didn't let it affect my life. I combined this journey with the visit to the relatives, took the train to one large city where I left my suitcase at the luggage storage at the train station, and then waited for like an hour for my next train. It was a small local train which took me to the small hilly town, with the castle in the middle of it, towering over the buildings. I walked most of the way. The icy sidewalks were the biggest problem but nothing too bad.
I arrived at the castle and had an interview with two elderly women. Everything went well… until the end. Only then they revealed that they actually had no intentions of hiring me and they knew it from the moment they saw my CV. Why did they invite me then? Well, they found my CV very interesting and wanted to meet me in person, but they had known the whole time that they wouldn't hire me. I’m not kidding. What was the reason? Well, I'm a foreigner living abroad and they said that they didn't want to deal with the “complicated insurance process”, so they couldn't hire me. I later found out that yes, it’s a complicated process but more for an employee than their employer (I've dealt with it at some later jobs – and also found out that a good and understanding employer can help a lot). And yes, they also violated the anti-discrimination laws.
Anyway, I felt like an idiot. I limped back to the small crowded train station and waited for the even smaller train. Time and money wasted on this. Don't do this. If you know from the very beginning that you don't want to hire someone (whatever the reason is), don't waste their time by inviting them for an interview, only to tell them at the end that you won't hire them because they are a foreigner.
