## How These Rankings Work

Scores come from **Google Reviews** via the Google Places API — never from paid placements, and never set by the agencies themselves. We apply a **Bayesian adjusted average** to prevent small-sample distortion (a 2-review 5.0-star agency shouldn't outrank a 200-review 4.8-star one):

```
adjusted_score = (v / (v + m)) * R + (m / (v + m)) * C
```

- `v` — total reviews across all offices
- `m` — prior weight (**20**)
- `R` — the agency's weighted average score
- `C` — the platform-wide mean

So with a global mean of 4.2: an agency with **5 reviews at 5.0** scores 4.36, while one with **200 reviews at 4.8** scores 4.75. The second outranks the first because the score is backed by more evidence.

Multi-office agencies get a single weighted score across locations. Every listing is human-reviewed before publication. Scores refresh hourly. [Read the full methodology →](https://recruiterrank.co/methodology)

## FAQ

### How do Iselin salary ranges for the most-recruited roles compare to national averages?

Iselin's concentration of pharmaceutical, healthcare IT and logistics operations pushes compensation above national medians for specialized roles. Clinical research associates and regulatory affairs specialists typically command 15 to 20 percent premiums over national averages, while software engineers in healthcare applications see comparable bumps. Administrative and light industrial positions track closer to regional New Jersey rates, which already run 8 to 12 percent higher than US benchmarks. The township's proximity to major pharma headquarters in Bridgewater and Princeton creates sustained upward pressure on technical salaries.

### What types of roles do these Iselin recruiting agencies typically fill?

Iselin agencies concentrate heavily on healthcare placements—registered nurses, allied health professionals and locum tenens physicians—reflecting proximity to major hospital systems throughout Central Jersey. IT and software engineering roles represent the second major focus, with particular strength in enterprise systems, cybersecurity and infrastructure positions serving corporate clients along the Route 1 and 287 corridors. Light industrial and warehouse staffing also features prominently given the distribution centers clustered around the New Jersey Turnpike. Administrative and accounting functions round out typical placement activity.

### What questions should I ask a recruiter before signing a contract?

Ask about fee structure upfront—contingency fees commonly range from 20 to 30 percent of first-year salary, while retained searches involve staged payments. Clarify the replacement guarantee period if a placement fails within 90 days. Request their average time-to-fill for your role type and inquire about their candidate sourcing methods beyond job boards. Understand exclusivity terms and whether you can work with multiple firms simultaneously. For Iselin's competitive corporate and tech market, confirm their local network depth and whether they maintain an active database of pre-vetted candidates in your industry.

### What's the difference between contingency and retained search?

Contingency recruiters earn fees only when a hire is made, typically 15 to 25 percent of first-year salary, and often work multiple openings simultaneously while competing with other agencies on the same role. Retained search firms receive payment in installments regardless of outcome—usually one-third upfront, one-third at milestone and one-third at placement—and work exclusively on senior-level positions with total fees commonly reaching 30 to 33 percent of compensation. Retained engagements include deeper research, market mapping and candidate assessment, while contingency focuses on speed and volume for mid-level roles.

### Is it worth hiring a specialist recruiter over a general staffing agency?

Specialist recruiters maintain deeper networks in their verticals and understand nuanced skill requirements that generalists often miss. In Iselin's corporate and tech sectors, specialists typically source passive candidates faster and assess technical competencies more accurately. However, they charge similar fees—commonly 20 to 30 percent of first-year salary on contingency—while serving narrower needs. General agencies offer broader coverage across multiple roles and faster pivots when hiring priorities shift. For senior technical hires or regulated industries like healthcare, specialists consistently outperform. For administrative or multi-department hiring campaigns, generalists provide better economies of scale.
