I applied online and heard back from the recruiter about 2 days later to schedule a screening call. The recruiter was really nice, very knowledgeable about the role and the team and was very transparent in terms of hiring process, requirements and salary range. They told me that this was the second time the team was hiring for this role because they couldn't find the right candidate in the first round. I felt very good after the talk with the recruiter and was looking forward to speaking with the hiring manager next. That call was set up 3 days later and was nothing out of the ordinary. Questions were all either specific to the role I applied for or about my past experience. Overall the call was fine but I personally prefer to have conversations rather then pure question/answer interviews. The next step was an onsite interview with 5 people (incl. hiring manager), which got scheduled about one week later and took around 3 hours. The experience was overall pretty positive, well organized, warm welcome and good conversations, however I got a weird vibe from a few interviewers, they seemed to be frustrated about Twitters challenges and didn't seem to be very happy there. According to the recruiter, the next and last step would have been another offsite interview with senior management but after I followed-up a few days later to ask about feedback I received an email with a home assignment instead, giving me 24 hours to complete. This is common practice these days but the recruiter hasn't mentioned that in our first call, so it seemed like this was not initially planned, also because the material I received looked like quickly thrown together. After I spent the entire evening and morning on it I received another email from the recruiter saying that I can take a bit more time to complete. As positive as the process was until then it went downhill from there. I had to follow-up multiple times with the recruiter to here feedback. At this point it was clear to me that I'm not their first choice and it felt like they tried to win some time by giving me the assignment. After a few more days and follow-ups I finally received a rejection email and felt pretty relieved.

I had a wonderful conversation with the hiring manager and was really excited about the opportunity. I was invited in for an on-site interview panel of 5 people from different teams. The recruiting coordinator who met me at the front lobby was very welcoming and made me feel accommodated throughout the day. The conversation styles ranged from the more casual to more formal interview formats, but not any unexpected questions. There were some creative questions to showcase my thinking process, and I was comfortable in my answers/the exchange. Altogether I was reading a lot of positive feedback from each interviewer's verbal and non-verbal queues. Then, the recruiter reviewed my compensation expectations and walked me through what next steps may look like. We walked around the offices to get a full tour before I left. I was told I would hear some feedback within the next few days. More than a few days passed so I followed up to see if there was an update. My recruiter had left on vacation and passed me onto his colleague. This is where the experience took a turn for the worse. Suddenly I went from clear consistent communication to radio silence. I continued to follow up over the course of several weeks to the point of giving up with no feedback from the process. Finally I was introduced to a friend of a friend who worked at Twitter and offered to escalate my case for me. Within a day I received a generic response that the team would not be moving forward with me. I found this lack of communication and lack of feedback after a lengthy interview process to be highly unprofessional.
