Case #0 - Replacing the Existing Development Team
We urgently needed to replace the development team on an existing project. As you understand, finding a team that fully matches the technology stack used by the existing team is quite a challenge. As you know, we have a large marketplace with more than 1000+ teams.


Technological stack: React.js, Node.js

We are aware of the strengths and weaknesses of many of them.

For this task, I immediately knew which team we needed. A few days later, we had an introduction meeting where we presented a well-coordinated team, consisting of an Architect, a Frontend developer, a Backend developer, and a QA tester.

A week later, the team started on the new project and began receiving information from the old team

Case #1 - Senior iOS developer for startup
The client, an USA startup, needed to find a Senior iOS developer who met their "challenging requirements" and also had to pass a test and discuss it with the technical team. We were not limited in time, but we understood that we had to start delivering new candidates within a week.

We had the client's requirements. The processes were launched. We prepared a job description for candidates, specifying all the requirements. A thorough selection of candidates began, checking their resumes, interviewing each interesting candidate, questions and answers. At each step, additional nuances appeared which we took into account.

Some statistics:
  • Total candidates who received an offer from us: 600+
  • We selected: 30 people
  • Sent to the customer: 7 people, each with a cover letter and a video interview with us.
  • Chosen by the client: 1 candidate, who perfectly met their requirements, passed all tests, and received a job offer.

As a result, we found the perfect candidate in 1 month. The client was satisfied.
Case #2 - Senior Android developer for product company
The client, a product company from Germany, needed to find an Senior Android developer who met their "challenging requirements" and also had to pass a test and discuss it with the technical team. Additionally, the client was also independently searching for candidates. We had about two months.
This task was typical for us. We discussed all requirements with the company's founder on a Zoom call. We received the tests that the candidate had to pass and agreed on the level of the proposed salary. A week later, we began delivering the first candidates.

Some statistics:
  • Total candidates who received an offer from us: 300+
  • We selected: 10 people
  • Sent to the client: 5 people, each with a cover letter and a video interview with us.
  • Chosen by the client: 1 candidate, who perfectly met their requirements, passed all tests, and received a job offer.

As a result, we found the perfect candidate in 1 month. The client was satisfied. The programmer has been working at the company for a year and is completely happy.
Case #3 - a large system company from the USA, needed to find Frontend + Backend developers, totaling 40 people within 3 months
The client, a large system company from the USA, needed to find Frontend + Backend developers, totaling 40 people within 3 months. The requirements were communicated by the company's representation in Bulgaria. Each time, the information was incomplete, complicating the hiring process. Ultimately, after the third iteration, we had a complete set of criteria for candidates. We had 3 months.

The task was unconventional and voluminous. A week later, we began delivering the first candidates.

Some statistics:
  • Total candidates who received an offer from us: 1200+
  • We selected in batches of 5 people, with about 70 people selected on our side
  • Sent to the client, got approval, conducted interviews: around 10%
  • Chosen by the client: 1 candidate, who perfectly met their requirements, passed all tests, and received a job offer.

As a result, we found a series of perfectly suitable candidates in 3 months. Apparently, there were some additional requirements that remained undisclosed. The client was satisfied.
