The guy went on for over half an hour, talking about the company and describing technicalities which seemed totally unnecessary at this stage of the process. The whole process was kind of chaotic cause he had back to back interviews. There wasnt really any meaningul question except for which technology stack I am familiar with. The interview ended with him saying and I quote: "I am gonna need you for a second half hour interview with our team lead engineer who is currently out of office, so you are gonna hear from me by the end of next week to schedule that." In the next few days I got a automated negative response :) No need to say something like that at all, just be professional and say the typical: you will be hearing from us either way.
