Perguntas de entrevista da empresa Techona

the interview was online and it was really good and smooth , they explain about the company and then i needed to talk about my self, and then we started the interview with solving some coding issues

It was not at all professional Interview, rather a big waste of time. They will call you share some details about the comapny and schedule you for the next round, where you will meet the management and some technical people, which will just ask about your backgroud and what do you do.. After some days they get back to you stating, 'Hey, our team is quite impressed with you and your profile' lets schedule the next round After that you are selected. then you have next round for the salary discussin and about the relocation.Whre you spend sometime with them discussing stuff about salary and other polices. Then comes the twist, the management is still confused to hire you,(waited for 1 week) Then another with the same management and then all goes well. One fine day, a follow up with them about the update of the interview feedback and final decision. So, they reject you stating okay, our management needs a different person for this role. Well, thats awesome, why were you impressed in the first place? were you not sure what to hire and what skills you need? All of sudden how come you can reject a person clearing all the rounds and you say you need a differenct person. Why shortlisted the resume then? Worst expereince ever i had in my professional carrer. I wont recommend this to any one.
