Interview started with a coding assignment, then tech screen call, then an onsite. The onsite was about ~3 hours long, with 3 different interviewers. The problems asked were very easy domain knowledge questions, and a couple of the algorithms they asked were also fairly straightforward. I got an offer the day after the interview, but I asked them to extend the offer deadline for about a month. The recruiter said there was no problem with this and we agreed on the extension. However, a week before the deadline date, they immediately rescinded the offer without even a warning or notice in advance. I did not care for the offer expiring, as I was not so interested in the role anyway, but this definitely left a bad taste in my mouth. It certainly does not help the "evil" stigma that Comcast has, despite their good benefits and a decent compensation package they offered me.
