Red Hat interview questions

I had extensive interviews that went on and on. I heard over and over again that there were two common elements of their culture: they are very collaborative and they move fast. For me, those two culture attributes collided. They collaborated so much that the interview process went on forever; anything but fast. I had over 11 different interviews and none of it moved quickly. I understand getting the input of hiring manager, their manager and a peer or two, along with HR. By then, the candidates character and experience is known and vetted. By trying to get everyone's option, they have analysis paralysis, and all that collaboration means the process then takes forever. What's more, after all those interviews it was hard to get anyone to respond for follow-up. I didn't get offered the job, which is okay, but at least have respect for the time we put in (almost 15 hours spent on interviews, paperwork and logistics) and have a quick de-brief call. In the end, I found out they wanted more experience within a specific sector. That was a frustrating answer, not because I didn't get the job, but that I told them my experience was limited in that sector from the very beginning; I never hid it, and I addressed it in all the interviews I had. If that factor had so much weight, I wish they had cut me earlier in the process versus wasting their time and mine. Then, I interviewed for another position, and essentially the same thing happened again. This time 6 or 7 interviews (some people twice). I was left a voice mail saying that I didn't not get that position because I again fell short of experience in a specific sector, which, again, I brought up from the very beginning. I know the company owes me no explanation, so I appreciate the initial call, and that they'd be willing to have a follow-up call to talk more. After that, not one phone call was returned. Again, if you're going to put a candidate through all that, please be respectful of their time (and that of the employees) to have a live 15-min debrief. It demonstrates respect and integrity. Between the two jobs, all in all, I think I spent 20+ hours interviewing. I'm all for collaboration, but you can't over collaborate AND have speed to impact. During this process, there was over-collaboration, that meant many valuable hours spent and decisions that were delayed. Which contradicts their idea of "moving quickly." This is a reputable company that I'd love to work for someday, so I'll likely continue to apply there, but I would tell anyone who's looking to interview that the process is detailed and very time consuming.
