Let me first say that Stephanie Bartels is amazing! I applied with the company earlier this month and from there the job hunt was on. Stephanie went above and beyond and made sure I had career opportunities within my field, salary and work culture. I would definitely call her "My Fairy Job Mother". Within 2 weeks of meeting her I had 2 interviews and an offer with a company that fulfills everything I was looking for in a career.

A company that I would of never found on my own. I consider it a "Big Girl Job". Benefits, 401k, PTO, you name it they offered it. I was amazed that Stephanie got me an Interview. She's not only a hard worker, she dedicates her time and effort to help build relationships to make it enjoyable. I'm forever grateful for this company and Stephanie. They changed my life for the better and I couldn't be happier. Thank you again for making this small journey fun and I'll recommend everyone to Keystone!

I learned about Keystone online and emailed to find out more. I was contacted by Stephanie who set up an appointment to talk with me. Upon learning that I was not interested in an entry level position(where she had placed many people) as a person with many years of professional business experience and 2 master's degrees, she went on to say that she would look for positions that were at a higher level and get back with me.

That was several weeks ago. Haven't heard from her since. My guess is that she either doesn't have non-entry level positions, or she just looks to fill these lower-level positions quickly because the commission she receives is high. In any case, a person isn't going to revert what they made upon college graduation when they've been out of college for 25 years. Disappointed that I wasted my time.
