Bloomberg Sr. Software Engineer interview questions

Apply online, telephonic screen sharing tech interview, onsite interviews. After clearing telephonic tech interview was invited for onsite interview. One day before the interview got a mail from recruiter that my interview was cancelled because the people who were supposed to be interviewing me were out of country. The recruiter asked for another dates. I wasted one holiday of mine as I already informed my current employer about time off with some reason. Recruiter SHOULD have informed me earlier, not only her fault but hiring process is flawed. For the new date recruiter informed me that I'll be interviewing for two teams and asked me book the entire day for them. Ended up interview only for one team in morning. Again wasted half of my vacation. She did not clarify why my interview with CIS team was cancelled for the second time.
