Contacted by a recruiter, the interview process was well-organized at the beginning.

I completed an online assessment.

Got a follow-up hiring manager interview. The feedback was good. I thought I was able to fly to the onsite.

After that, it became poorly organized. I didn't get any schedule information. They suddenly called me when I was outside, saying that we have more tech questions to ask you and I need a computer. I thought the next might be a coding round, so I made the schedule.

On that interview day, the dirty thing is, they didn't ask me to do any coding test, except for keeping asking me the exact same questions that were already asked by the hiring manager in the previous round.

I was quite confused why other interviewers didn't make good coordination with their hiring manager, keeping asking the same questions to waste my time.

They are C++ try-exception fans. Be prepared for this area if you want to join them. Also, HTTP and SSL stuff.
