You complete a straight forward multiple choice type application online and passing this you are invited to take a lengthy interview process in an Assessment Centre in West Kensington. At the Assessment Centre, there can be up to 20 candidates invited to take part. As explained by earlier candidates - the interview is formed of 3 stages: Test, role play and interview. The test takes about 75 minutes in classroom exam style setting; has two parts and covers questions about tube map and travel. Please be aware that they are also monitoring your spelling and grammer and you will get 'eliminated' for errors. In this round - a great number of candidates can be eliminated. If you are successful in the first round - you will be put forward for the role play - which an assessor explains that it will take about 10 minutes. Role play varies and they use very good staff/actors who can play all sorts of parts which imitates real life situations you are likely to encounter whilst working as a CSA. The objective of this part is to assess your customer service skills and confidence. As other candidates have mentioned - this can be a tough round and many are unsuccessful here. It's best to be yourself and read clearly your task before the role play starts. Treat the customer how you would want to be treated. Final segment is the actual interview itself whereby you are asked questions based on the CV you sent and to give examples of customer service based job of dealing with difficult situations involving the public etc. These can last upto 90 minutes (mine did)!! Put it this way - if you have an interview lasting longer than 20 minutes, you're on the right track. Once done, you'll get a call depending on how busy they are etc on whether you're successful etc - most likely you are. I took my assessment interview on a Friday and had positive outcome on the Monday. You then go on to have a full medical with Occupational Health as well as complete your employment verification with Sterling BackCheck (an external referencing company). Once all passed, you wait for training dates to come up. You can be waiting upto and beyond a year depending on how many training slots they have available. It took a year for me but only because I was too laid back in sending referencing information etc. Also you need to provide drug & alcohol test and update on your employment every 6 months prior to commencing training. Training can be up to 5 weeks full time (9-5) depending on your role.
