Candidate Testimonial:

Abby is awesome and was an integral part of my job search. She first helped clarify my own half-baked thoughts about what my next role should be and worked tirelessly to find opportunities that suited those requirements. She got those companies excited about me, to the point where I could clearly distinguish which opportunities she had sourced and which ones I had just by the initial tenor of the conversation - it literally felt like a cheat-code!

Navigating a bunch of disparate job pipelines is annoying at best, but Abby stayed on top of everything and knew exactly when to prod a company (or me!) to keep everything moving forward. When we got to the offer/negotiating phase, she walked me through exactly how it worked and how best to structure my asks to reach my targets.

Abby is quite literally the best at what she does - I would work with her again in an instant. I’ve already told all of my friends about how working with her felt like playing a game on easy mode and would encourage anyone and everyone to work with her.
