I've applied for the LNER London Kings Cross talent pool.
So far I had to i) submit the application with the CV and certificates, ii) do a five question typed answer interview with an AI chat bot (no time limit at all), iii) do a video interview with the AI chat bot (also no time limit), iv) do a 15 question SJT with a 25 minute limit, and then v) do an error checking test with a 10 minute limit.
I did not get a confirmation email after the error checking test but I got a 'you're through to the next round' email after a few minutes on every other part of the process.
It is surprising how varied the application process is for LNER roles.
