We are expanding our operations to Hungary 🌍

🎙 “Quality equals the right combination of expertise and communication, and our corporate culture follows this philosophy in every way,” says Eyal Zucker, the managing partner of Exadel Hungary.

He further elaborated on the expansion, stating that, in the future, the Hungarian branch will be one of the major hubs of the company, serving international clients from all corners of the world.

🎙 "In Hungary, Exadel is still a startup with a family atmosphere, serving large international corporations with its unique IT solutions. We are familiar with both business models, so we know how to combine their advantages.”

The majority of Exadel employees work fully remotely, with the freedom to work from home or travel wherever they would like.

Good recruiters know how to interview candidates. Perfect recruiters pass interviews with flying colors themselves 🌟

Read our top tips to tackle a job interview for a Recruiter’s position at Exadel! 👇

📌 Research information about the company beforehand.
A candidate’s questions are the best indicator showing his/her interest in getting a job there. Ask about everything: recruitment process, projects, team, KPI, etc.

📌 Get technically prepared.

This is commonplace advice but often overlooked by candidates. If you have little experience, learn in detail the search tools, where to look and how to hire, how to make the first contact with candidates, etc. Be sure to repeat how to work with Boolean Search. This is an integral part of a recruiter’s job, even if you use other programs for making requests. It is important to understand the essence of the request, and variants of special logical operators, thanks to which you can process a huge flow of information and get relevant results. And, of course, be prepared to talk about your work experience.

📌 Explore the hiring process in your location and other European countries.
It’s great if you are aware of trends, know popular job boards, and understand the main types of contracts.

📌 Forget the myth that without experience, it is impossible to get into a good company.

We at Exadel are always ready to consider newcomers and help them get started. If you don’t have experience as a recruiter yet, but you are trying to fill in gaps in skills and knowledge by yourself, study the differences between tech stacks, if you are proactive and can think on your feet, the doors of Exadel are open!

📌 Check the sound quality and PC performance before the interview and turn on your webcam.
Moreover, for a recruiter a camera is one of the working tools, it must be set up and stable and ready to go at all times.

📌 Remember that an interview is not an exam or an earth-shattering event in life. Don't be too worried.

This is a conversation between two people united by one goal - to connect a worthy candidate and a good position. An interview is a valuable experience. Even if, for some reason, you do not receive a Job Offer, you’ll receive feedback that will help you analyze what was missing and what you should pay attention to next time.

📌 Try to be in a good mood!

If there are any issues and concerns, it's better to resolve them in advance, than come to the interview with doubts and anxiety. It is always nice to communicate with a positive-minded, affable person. Then time slips past, and there will be no unnecessary stress.
