It was the most harmful experience on my job hunting track. For 3 month I went through 2 logical test, 3 interviews and in the last one I got a great email saying "Smoooth news for you! Our team is very interested in your profile, and we want to schedule the next 2 interviews with you now". Got really exited at this point, both interviews were schedule for the same week and the last one was for "meeting the team".  Because of that I spent the entire weekend preparing a presentation, learning a lot about Klarna, listening Podcasts about BNPL, etc. I was ready for that opportunity I was looking for. The first interview on that week was meant to be on Wednesday, and I got an email the day before saying that they were both appointments were cancelled. With no further explanation. I asked for some feedback, to understand if I did something wrong, or if the process was ended in that unexpected way, but nobody answered.  After a week and a couple of emails, I got a call saying that they have chose another candidate. I never got the chance to present my profile to the last person that would took the decision, spent an entire week feeling the injustice and failure of a very inhuman process.  To sum up, I believe that the best way "to improve the experience" is to treat candidates as peers and not as an ID code in a database.
