I've now interviewed twice with Regus, both times I had excellent interviews in which the interviewers told me that I would definitely move on to the next step (I make a point to ask this question in all of my interviews). Both times I've received absolutely NO follow up, despite my sending follow up emails, etc. I should note: Regus recruitment reached out to ME both times, not the other way around.
I completely recognize that this down economy fosters an environment in which employers feel that they can disregard the standard interviewing courtesies, since candidates appear to be a dime a dozen. That said, employers (Regus) should recognize that qualified, respectable candidates are also interviewing the company to determine whether it's a good fit for them in the long run.
The interviews themselves were par for the course; strengths, weaknesses, why would you be a good fit for this position, how do you feel about being a "hunter" for new business, what makes you unique as a seller, etc. I got the impression that you work a lot of hours for your commission, and it's unacceptable to be less than 100% of quota attainment, ever. Having been in sales for years, this is nothing new to me.
Based upon my experience, I've determined that accepting a position with Regus would not be a good move for me.
