I did apply for the position using online for. Got a call from my tights and was invited for an interview. Via the phone they were not very open for questions. They informed my only that it would be a little trial plus the questioning immediately after. I had a previous experience for this role.
At the day of the trial there was not much of a chat, I was soon presented to a main warehouse employee (lady) who was actually detailed. She explained me what to do (pick the items for some orders). There were 10 orders to pick up from all the different places and boxes. It took me nearly 10 minutes. All the picks were correct.
Immediately after the customer service lady were called. She made me 3-4 questions overall. Before leaving she said they would notify me in two days about the decision. That didn't happen and so, I very politely followed up after 4 days by e-mail. I wanted to know whether they decided something or not so, I could go on with my other offers. My e-mail has never been replied (what I personally find very rude).
*The whole process (being me there) took something as literally 15 minutes (trial+questions).
