Lucky for me, every day is Saturday!
The recruiter emailed me late yesterday and asked if we could catch-up on Monday. One of the most unprofessional emails I've ever received. That message was in the subject line. The body was completely empty except for the corporate legal disclosures.
I've interacted with several people from this firm and everyone was great. If this recruiter had been my first impression I would have run from the hills a long time ago.
