Hiring your first employee is one of the most important and delicate steps for any business owner or sole trader. Taking this leap means moving from managing all tasks alone to leading someone else and building a shared working environment. However, this process often raises administrative, financial and organizational questions about how to proceed properly without taking unnecessary risks.

To approach recruitment with confidence, it is essential to plan every stage before posting your first job advert. Knowing the associated costs, organising the legal formalities and identifying key interview questions will enable you to make sound decisions and save time.

1. What to decide before posting a job to hire your first employee

The most common mistake when hiring a first employee is publishing a job advert without analysing its financial and operational impact on the business. Before advertising any vacancy, you must clearly define the profile you need and your business's actual capacity to take on that new hire.

  • Real budget and associated costs: in addition to the agreed gross salary, you must consider employer Social Security contributions, which represent an extra 30% to 33% on top of the gross salary.
  • Contract type and working hours: evaluate whether your workload justifies a full-time position or if it is better to start part-time, selecting the most appropriate contract type available.
  • Specific duties and responsibilities: draw up a list of the priority tasks the new employee will take on to avoid any ambiguity about the role during recruitment.
  • Workplace setup and equipment: ensure you have the physical space, IT equipment and software licences required so the employee can start working smoothly from day one.

2. Steps to complete the hiring process in order

Following a logical sequence simplifies regulatory procedures and reduces the time needed to onboard the right candidate. The recommended steps range from initial administrative tasks to signing the employment contract.

  • Social Security registration: if you are hiring for the first time, you must register your business with Social Security and obtain a Contribution Account Code (CCC).
  • Drafting and advertising the job post: detail essential requirements, working hours and offered terms. Using platforms like JOBO helps organise your company's hiring process and manage applications centrally.
  • Initial screening: review received CVs, filtering those that meet essential experience criteria, and conduct short screening calls to confirm availability and interest.
  • Assessment interviews: invite the most suitable candidates to discuss their technical skills and working style in greater detail.
  • Employee registration and contract: register the worker with Social Security before their start date and formalise the employment contract in writing.

3. What to ask during job interviews

When an SME or sole trader is hiring their first employee, initiative, self-reliance and adaptability are just as important as technical experience. Questions should focus on specific situations the candidate has handled in the past.

Situational and behavioural questions

By asking questions based on past experiences, you can assess whether the candidate can make sound decisions when unexpected issues arise or when direct supervision is not available.

  • Could you describe a previous work situation where you had to solve an unexpected problem without direct guidance from a manager?
  • How do you organise your daily workload when several priority tasks overlap?
  • What methods or tools do you use to ensure you meet your deadlines and commitments at work?
  • What factors do you value most when joining a smaller business project?

4. Onboarding and initial integration plan

The recruitment process ends with properly integrating the individual into the role. Preparing a two-to-three-week onboarding plan helps the new employee understand company dynamics, grasp their initial goals, and gain independence more quickly. Scheduling brief check-in meetings at the end of each week helps clear up doubts, coordinate tasks, and strengthen the working relationship from day one.

Frequently asked questions

How much does it cost to hire your first employee in Spain?
In addition to the agreed gross salary, the company must pay employer Social Security contributions. This contribution usually represents an extra 30% to 33% on top of the employee's gross salary. You should also consider indirect costs such as occupational risk prevention or professional advisory fees.
Is it mandatory to hire an agency or advisor to register the worker?
No, it is not strictly mandatory, as the procedures can be carried out directly via the Social Security online portal if you have a digital certificate. However, having the support of an employment advisor or gestor is highly recommended to ensure correct alignment with collective bargaining agreements and to avoid compliance errors.
What preliminary procedures are required before signing the contract?
Before formalising the hire, the company must apply for registration as an employer and obtain a Contribution Account Code (CCC) from Social Security. Additionally, you must register the worker prior to the start of their working day and formalise the contract in writing using the official template.
