The interview process took nearly 2 and half months which is considered too much time with unclear image of the process. They asked first to finish an assignment which took about one week with 24/7 working hours to finish. After this, I received no reply. Lately after contacting them they asked for finishing another assignment which was verymuch complicated and took nearly 2 weeks to finish. After all this process I got no reply. After contacting them again for the fourth time I got an email with the refuse for the job offer. Things were so unprofessional and unclear and it ended up with nothing .
