@dmc02 Yes. We were sent home at lunch. I got two emails, one inviting me to stage 3, and another asking me to take a 40min Occupational Personality test online, a link for which would be emailed to me. Presumably the online test was the same as the afternoon one we missed. However, I haven't been sent a link to the online test, and have emailed HR about it.
Bit worried because the email regarding the online test said it needed to be taken before the application process could continue.
