5. Post your job

   To find the right senior hydrogeologist for your business, consider trying out a few different recruiting strategies:

   • Consider internal talent. One of the most important sources of talent for any company is its existing workforce.
   • Ask for referrals. Reach out to friends, family members, and current employees and ask if they know or have worked with senior hydrogeologists they would recommend.
   • Recruit at local colleges. Attend job fairs at local colleges to recruit senior hydrogeologists who meet your education requirements.
   • Social media platforms. LinkedIn, Facebook and Twitter now have more than 3.5 billion users, and you can use social media to reach potential job candidates.

   Post your job online:

   • Post your senior hydrogeologist job on Zippia to find and recruit senior hydrogeologist candidates who meet your exact specifications.
   • Use field-specific websites.
   • Post a job on free websites.

6. Interview candidates

   Recruiting senior hydrogeologists requires you to bring your A-game to the interview process. The first interview should introduce the company and the role to the candidate as much as they present their background experience and reasons for applying for the job. During later interviews, you can go into more detail about the technical details of the job and ask behavioral questions to gauge how they'd fit into your current company culture.

   Remember to include a few questions that allow candidates to expand on their strengths in their own words. Asking about their unique skills might reveal things you'd miss otherwise. At this point, good candidates can move on to the technical interview.

   The right interview questions can help you assess a candidate's hard skills, behavioral intelligence, and soft skills.

7. Send a job offer and onboard your new senior hydrogeologist

   Once you've decided on a perfect senior hydrogeologist candidate, it's time to write an offer letter. In addition to salary, it should include benefits and perks available to the employee. Qualified candidates may be considered for other positions, so make sure your offer is competitive. Candidates may wish to negotiate. Once you've settled on the details, formalize your agreement with a contract.

   It's equally important to follow up with applicants who don't get the job with an email letting them know that the position has been filled.

   After that, you can create an onboarding schedule for a new senior hydrogeologist. Human Resources and the hiring manager should complete Employee Action Forms. Human Resources should also ensure that onboarding paperwork is completed, including I-9s, benefits enrollment, federal and state tax forms, etc., and that new employee files are created.

8. Go through the hiring process checklist

   • Determine employee type (full-time, part-time, contractor, etc.)
   • Submit a job requisition form to the HR department
   • Define job responsibilities and requirements
   • Establish budget and timeline
   • Determine hiring decision makers for the role
   • Write job description
