Cortica Software Engineer interview questions

Sent me a home assignment, called me to say i passed the test and set an interview, told me to wait for confirmation on the date, didn't talk to me for 2 weeks and then sent me an email that they continued with someone else. that would be fine if they were honest with me and not let me wait weeks without hearing a word from them. very bad experience, they totally disrespect candidate, and might i suspect employees in general.
