At Reality Games, we believe in creating a smooth and transparent recruitment process to ensure a positive experience for all candidates. Here's a glimpse into how our recruitment process typically unfolds:

Step 1: Let's Get Acquainted (up to 30 min) First things first, let's grab a cup of coffee (or tea if that's your thing) and have a casual chat. We want to know more about you, your background, and what makes you tick. We'll discuss various aspects like your previous work experience, your notice period, and any other details related to your current organization. It's essential for us to understand your situation and ensure a smooth transition if you join our team. Don't worry, we won't keep you stuck in a never-ending conversation, just enough time to get to know each other better.

Step 2: Building Trust, No Live Coding When it comes to assessing your technical skills, we want to provide a stress-free experience. Instead of putting you on the spot with live coding challenges, we'll give you a take-home assignment. You'll have plenty of time to work on it at your own pace and showcase your problem-solving abilities in a comfortable environment. This way, you can focus on delivering your best work without the pressure of a ticking clock.

Step 3: Meeting the Tech Gurus (up to 60 min) You've made it past the initial round, congrats! Now, we'll bring in the big guns. You'll have a chance to meet with a technical expert or team leader. They'll dive deeper into your technical knowledge, ask you some specific questions, and see if you're a good fit for the team. Think of it as a friendly chat with someone who knows their stuff.

Step 4: The Feedback Loop Once all is said and done, we'll gather feedback from everyone involved in the process. We'll review your performance, take into account the opinions of our team, and make a decision. If you're the lucky candidate, we'll be thrilled to have you on board. If not, don't sweat it. We appreciate your effort and there are plenty of other opportunities out there.
