First round interview with HR lady, hiring manager and staff from the department. They asked pretty standard interview questions. Do note that they have a small team and that they are very picky about who they select to join the team. In addition to an interview there will also be a stats test and a personality test. The stats test requires you to plan an experiment to find out how to best improve the efficiency and customer satisfaction at check in counters as well as a data sheet that you are required to analyse.
