In terms of the selection process there is 2 stages.
1st interview will be with a recruiter of the location, where they will explain to you about what they do and what they are looking for.
2nd interview will be with the owner or a business partner of the location, where they will go into even more detail about the company and the growth within the business. You will also have the opportunity to observe the environment.
Just be yourself, because those are the people standing out and that is the kind of people Optex Group wants. Never underestimate yourself. If your dreams doesn't scare you then it's not big enough
