Here’s how we get from first “hello”

You’ll meet with our HR team to discuss your experience, approach to software development, and teamwork. We’ll also verify your English language proficiency as part of the conversation. Then, you’ll take part in a technical interview focused on your skills and problem-solving mindset.
If both interviews go well, we’ll match you with a project aligned with your skills and expectations. You’ll then meet the client – this is where the final project-related decision is made.
Based on feedback and your preferences, we’ll prepare an offer tailored to your experience. We’ll agree on the project, salary, type of contract, and your start date.
We start with a short phone conversation to get to know each other. We’ll talk about your experience, career goals, and motivation, while giving you a chance to learn more about Jit Team and the role.
Depending on the role, you’ll complete a short recruitment task to showcase your skills. We’ll also verify your English language proficiency as part of this stage.
Next, you’ll meet your future Team Leader at our office. We’ll discuss your experience, ways of working, and how your skills match the role, while giving you a better understanding of the team and day-to-day collaboration.
If we’re a good match, we’ll prepare an offer tailored to your experience. We’ll agree on the salary, type of contract, and your start date. Welcome to Jit Team!
