Solution
We scrutinized the project and job descriptions. We held video conferences with the client to clarify the details we were interested in.
Next, the IT recruiter made a preliminary selection of potential candidates with the required skills and a suitable location. After sending out the project description and job description to the candidates, the first feedback was received and interviews with the candidates were scheduled.
As a result of the interviews, detailed profiles of relevant candidates were sent to the client. We then scheduled interviews with the client's company representatives and candidates.
A total of 3 stages of interviews were conducted with each candidate, including stakeholder interviews. As a result, job offers were made to the final candidates.
Results
Out of 112 job postings sent, we attracted 22 qualified candidates, of which 6 reached the final selection stage and 2 joined the client's team and are successfully employed.
