First round HR interview (Salary expectation, position description, agreement of the general process)
Second round Management interview, general troubleshooting questions, personal questions, not difficult at all.
Then they send you a set of questions to investigate and do (How a traceroute works, what it does) (General questions of how ThousandEyes agent is installed)
Third round, questions regarding your answers of your assignment , dig into networking general concepts and a little bit of linux.
Then I received a call from the recruiter, telling me they wanted to make me an offer and that they would like to continue the hiring process. 2 weeks later, sent an email regarding, no answer, 1 month later another email no answer so far. What a waste of time to do the whole interview process, get accepted and then being ghosted, what a bad way to do things.
