Bloomberg Senior Developer interview questions

I applied online on May 7th. I heard back the next day that they wanted to do a phone screen with HR. I setup that call and all went well. This was when I first noticed that the recruiter (maybe just HR person) was rude and cold. They were not like the other recruiters I've worked with in my job search process. I didn't think much of it at the time. From there I did the tech phone screen on June 3rd. I heard back on June 7th that'd I'd be moving on to the virtual onsite. I scheduled my onsite for June 17th. They were very vague about the onsite and said I could schedule a call with the person I first talked to (hr/recruiter?) to learn more. I setup the call for June 11th. They never called... this should have really been a red flag for me but I still continued... When I logged into the virtual onsite I was greeted by 2 disinterested engineers that immediately just started talking without even greeting me. Throughout the interview they just seemed disinterested in what I had to say and many times they were silent after I was done speaking. The next interview was better but one of the engineers had a bad internet connection and so I barely could understand them. At the end of that interview they said I could take a 20 minute break and that someone would join the call after that. So I take a quick break and get on the call again. I wait 5 minutes, no one showed, 15 minutes, still no one... I wait 30 minutes and still no one joined the call. I emailed the only contact I had and luckily they got back and said "Oh I'm sorry (the recruiter/hr) person was supposed to join the call but got pulled into a meeting last minute. I think you already talked to her today though so you're done for the day". I had in fact NOT talked to her yet AND she failed to show up AGAIN. So unprofessional and completely rude. I was really thinking I'd like Bloomberg as a place to work but after this experience I will never apply again. This was such an awful experience as a candidate and I think they should really look into the HR/recruiter person I was working with. I heard back 2 days after the onsite that I was rejected.

1 coderpad and 2 virtual onsite with 2 engineers in each round. Both the virtual onsite rounds were DS and Algo questions. No system design. Rejected after a week
