Not interested HR, asking all usual behavoiural questions. Being rude and being late for the meeting. Expecting 5 hours Engagement from candidate for few rounds of interview. Calling me after 18:00 casually in the middle of the week, without further notice.

Lots of consulting-type questions. I suggest preparing for this to get used to the line of questioning. Sample types: How many ping pong balls can fit in a Boeing airplane? What is x multiplied by x? The goal is not to have a correct answer, but for them to understand your line of thinking
