Tips & Tricks to Nail Your Interviews!

Since we want to keep everything fast and easy for you, we don’t want you to waste time on a cover letter – we would rather take a look at your CV and if it’s a match, we directly invite you to a first call.

Test your internet connection, camera, mic, and speakers beforehand. Time for each interview is limited, and we’d like to spend as much of it as possible on getting to know each other. If the interview is online, always have your camera on! It’s way easier to create a meaningful interaction if we also see each other.

We will give you all the information about the role & company’s culture, but it’s always nice to see how you perceive us after doing some online detective work.

We will certainly ask you to briefly summarize your work experiences in a short overview. Think of what you’re going to say beforehand so you can fit all of the essential information in 2-3 minutes. Keep the goal of the interview in mind, and make sure everything you say is relevant to the position you’re applying for.

Be specific, but don’t get caught up in details – following the STAR method can help you: Situation (set the scene and give the necessary details of your example) – Task (describe what your responsibility was in that situation) – Action (explain exactly what steps you took to address it) – Result (share what outcomes your actions achieved).

It is a recruiting process, but this doesn’t mean you can’t loosen up and showcase your personality. We are looking for an authentic character and we are open to having some small talk or a funny joke thrown into the mix. This might even show us that you’re a good cultural fit. Remember, next to all our ambition we like to have fun!

At the end of the interview, we will ask you whether you have any questions for us. Use this time to get answers to all your questions or clear out any curiosities. Always have two or three questions prepared, whether about the position specifically or about career development, upcoming projects, or company culture.

Even if you’ve already scheduled an interview, urgent things might pop up in your schedule or you might not feel fit to attend the interview. We are all humans & we treat these situations with empathy. It’s better to reschedule rather than not be 100% prepared to attend the interview. Simply communicate the change with your TA Manager and we will find a solution.
