4 rounds of interview, 1st HR, 2nf Technical, 3rd Cultural fit, 4th- on site where I also had to showcase my skills by following a recipe. Overall experience was good but the interview process took longer than 2 months

The first interview was ok, very friendly and relaxed. For the second step, I was asked to develop a project - which took me a lot of time, money and energy - and I had the feeling they led me to the wrong direction, to "trick" me and see my reaction while presenting the project. I don't feel that's very nice or honest, and it gave me a very bad impression of the company. Especially considering how much effort I put into the project and how careless their feedback e-mail was.
