I applied in April and got the job in December but didnt start training till January, so it's a long process with a lot of steps on the way. I think this is for safety purposes which make application processes very thorough, as there are significant safety risks involved with the tube.

I applied online and was invited to the first assessment centre which involved ticket checking and grammar/spelling tests. I found this to be very basic. The sample tests will help you know what to expect as the real test is very much the same format as the practice paper. I was then invited 2 weeks later for the role play and interview. Role play was a very basic scenario and all you will need to do is show your customer service skills. They give you a brief to go over before role play, make sure you stick to what it tells you to do and you will be fine. Interview was quite relaxed, definitely try and think of some examples from your work or study experience beforehand though. I made a list at home of situations which matched up to the competencies they were looking for and I felt much more prepared at the interview than if I just went in having not thought of examples. My interview lasted around 20 mins and I had 4 questions. Don't worry about missing out on anything as the interview will probe you for more details if they need it. I heard back 2 weeks after interview with the job offer. Overall I'm happy with how easy TFL made the process and their recruitment team are all friendly and do the job well. They are quicker at most other transport companies I have applied for in the past which is great.
