How does a recruitment tech company work?

There are three main topics to cover regarding how an agency works: sourcing candidates, billing, and type of talent provided.

Sourcing technical candidates

When it comes to finding the best technical candidates, recruiters have a tough task on their hands. With tons of competition, recruiters can struggle to catch the eye of the best candidates. And since it's known the competition is high, candidates expect to negotiate favourable offers and a level of service similar to what they receive from B2C companies.

That's why staffing companies are turning more often to recruitment agencies technology. An applicant tracking system (ATS) like Bullhorn helps recruiters to provide a seamless experience. And when complemented with a VoIP phone like Ringover, recruiters can then leverage omnichannel communications to reach candidates where they are at. You'll have your call logs easily accessible, so any recruiter can pick up the thread of a conversation. And when you are hunting for a specific position, you will be able to increase your efficiency thanks to features like click-to-call and call campaigns.

Billing

In terms of billing, usually a recruitment firm will charge as a percentage of the hired candidate's salary. But there are a few different ways in which the fee can be paid:

• In advance of a successful hire
• In stages depending on hitting deliverables
• Once a hire has been successfully completed

There are then two types of hires, which reflect the two basic types of hiring contacts employers can offer candidates.

Talent Type

Contractors

In this scenario, the agency will actually hire a worker to supply for the company in need. The contract worker will be employed for a specified amount of time and can either negotiate a lump sum or an hourly rate. The agency will then also charge a fee on top of the worker's pay. In the event the client company wants to hire that contract worker into a permanent position, the agency may also add what's called a contract-to-hire fee.

Permanent placement

Also known as a direct hire, in this case the recruitment agency will hire a worker on an indefinite contract for the client company. In this type of hiring, the agency's fee is usually a percentage of the new employee's salary–generally 20-30 percent. However, that's a regular hire. The fee can be higher in complex cases.

How to select the best technology recruitment company?

The technology recruitment companies listed above can all deliver the end result needed: qualified technical candidates. But, certain elements can make all the difference in your experience. After all, if you need to hire a large technical team, or if you have a large project that requires a small selection of freelancers, your requirements will vary drastically. Here are the major factors to consider when considering what recruitment tech company to hire.

1. Confer with your contacts in your industry to see if they have any experiences in this field. After all, if they have successfully hired talented and knowledgeable technical team members, they can potentially provide insight into how to organise your process.
2. Confer with any hiring staff in your company to see if they have previously worked with a staffing agency and can recommend one.
3. Create a list of the IT recruitment agencies that appear to have a strong potential to serve your needs.
4. Contact your potential choices to solicit key information like budget and whether the candidates they placed at other companies were retained.
5. Reduce the choices you're considering to two or three based on the information you gathered in the previous step. Just be sure you don't fall into the trap of choosing an option because it's significantly less expensive–this can often equate to a poor quality of service or worse, candidates.
6. Finalise the quotes and services with your final choices to determine which one is most aligned with your current needs.
