This is a top notch staffing agency. Kayti contacted me in late May about working with me to find a job and by the end of June I had an offer. They are very responsive and give you all the tools needed to assist you in your interviews and follow ups.

I worked with Angela Fraguela. What an awesome individual. She never gave up on me. She worked tirelessly to find me a job. She's so friendly and personable. The job that they do is not easy. They're trying to please both the client and the potential employee. That's hard to do. Angela has always been positive and open with me. It's been a very long time since I've had someone work so hard on my behalf. I appreciate you, Angela!

I had a not so great experience with this agency, I was contacted Jeff Hershfieldy, went for an interview and provided all my documentations. He made believe they had a few opportunities he was going to submit me for. weeks went by and never receive a call. Whenever I called to follow up he never even remember who I was. Later he tried to send me to a temporary position at a horrible office in the Bronx with very bad reviews.

He called back several months after offering the same position at the same place trying to make me believe it was a different organization, but I remembered the location. He tried hard to make agree into going there even when I explained to him he had contacted me moths before with the job. I explained I was not looking for 3 or 4 weeks assignments and that the Company had Horrible reviews. I never contacted him again and never heard from him again. A complete waste of my time and Metro card money.

Don't waste your time here. Jeff will meet with you, has you fill out tons of paperwork, and promise to follow up, and literally falls off the face of the planet. Even when you reach back out to get an update, he just confirms that you're still available (maybe to pretend that he's searching for you), and when you tell him that you are, he just responds "okay" and continues to be MIA. On top of that, the front-desk girl is vicious! Girl, put a smile on. Seek another agency. There is no relying on Abacus Group. They are terrible overall.

I worked with Emily during my job interview process. She contacted me on LinkedIn and the jobs she mentioned seemed really interesting to me. She was very accommodating of my schedule as I was in the middle of busy season. Throughout the whole process I never felt pressured and she always gave me adequate time to get prepared for the interview. Her interview prep calls were always super helpful. After a few weeks of interviews I accepted a full time position. I've started at my new job and could not be happier with the placement. Using this service was such a stress reliever for me and I would definitely recommend others give it a try.

Had a great experience with Greg. He was very straight forward and honest. We were able to have a clear direction of the role I was looking for and I knew that he wouldn't waste my time with roles that wouldn't interest me. Greg was able to find me a wonderful role at a large bank. Greg was a huge resource and I'd recommend him to anyone looking to further their career!
