Had an introductory interview with one of the executives, which was postponed 2 times before actually taking place. Mostly asked to recite my resume and explain what types of clients I'd be interested in working with based on my experience. Then, received a "homework" in the form of a 4-hour case study basically doing free business development for them. Waited for a reply/feedback for a month, then got a few lines explaining the position is not open anymore. Absolutely would never apply there again.
