The process took 4 weeks. I interviewed at Blackstair (Oak Brook, IL) in Nov 2018
Interview
1 round of HR screen
1 round TPS(technical phone screen)
Onsite---3 rounds of technical, 3 rounds of management.
The atmosphere in this firm is amazing, small tight knit team, makes you feel like everyone knows their stuff and doesn't waste any time. Definitely "NOT A NURSING HOME" . Very considerate during the interview, probably the best office hardware I have ever seen ,40 inch monitors and top floor in the 15 mile radius. Very Nice.
Interview questions [1]
Question 1
A lot about comp sci basics, data structure, algorithm, threading, socket, system design. Some mathematics, linear algebra and a few brain teasers here and there.
Extensive coverage but mostly easier questions.
