Cisco Software Developer (Python) interview questions

Process was quick and straight forward, 3 interview 1 behavioral and 2 technicals. First interview was with the recruiter then second and third were with technical leaders of 2 different teams.

There were 4 rounds all in same day. After all rounds hr told me that i am selected and that he will share offer letter soon(he also took my documents as well). Few days after repeatedly ignoring my calls he tells me that they have hired an internal candidate. Please don't interview for this company, they pay in pennies and the hr are very arrogant and rude. Worst hr don't care about the interviewee at all, don't waste your time interviewing at this company.
