I had one online English Test, One Technical Interview, then I passed successfully and next step was 5 interviews in one day, from 10am to 4pm, I faced algorithm issues, I successfully done them, I assure to have a good attitude, I even accept improvements to the solutions I have implemented, I ask if they were better solutions than the ones I've provided, and with no feedback or reason at all, I was rejected !!!!!!!!
I accept that I could say something wrong or something that could misunderstood, I'm not perfect, but why I didn't received any feedback at all...
My guess is some of the interviews doesn't like me, as i knew a couple of them, if it's the case what a professional company this is...
