Uber Software Developer interview questions

Uber was far too slow throughout the entire process. They told me in mid-September that they wanted to interview me, and from the very beginning, I told them that I had a deadline of November 1st with other companies. It took them almost an entire month to finally schedule the interview, during which, I contacted my recruiter multiple reminding him of the deadline and he assured me that I could complete the process with Uber in time. When they did finally get back to me, the phone interview was scheduled for Mid-October, which I passed. Afterwards, I get an email asking me to give them my availabilities for an onsite. I list them, but the only time they had listed was the end of October. I responded within minutes of receiving the email and asked for the earliest of the days, he listed, but also asked if it was at all possible to do it earlier. Instead, he took a full day to respond telling me the day I chose was full, and the earliest I could do was days later, and as such, I wasn't able to do the onsite.
