The longest process I've been through, taking about 3 weeks from application through to recieving their decision. I was surprised to be invited for an assessment day following a phone interview and written test. As the first written test was given to be completed over a weekend, I ended up spending at least two hours (if not longer) completing it. However, the written test on the assessment day was very similar but we were only given 45 minutes, so the majority of us couldn't even complete all the questions let alone answer them as thoroughly as we would have liked. Throughout all three stages, the company's 'feedback culture' was constantly mentioned, so although they didn't give me an offer I was confident that they would provide me with feedback to help in future interviews. However, it was very vague and they simply mentioned that I didn't show the level of problem solving skills they wanted in the tests undertaken on the assessment day. They didn't expand on this to tell me exactly what aspects I could have improved on, so ultimately their feedback wasn't very constructive or useful at all. It's a shame because the atmosphere made it seem like a really lovely place to work, and to spend the best part of a month applying for a job I genuinely think I would have enjoyed (and been good at, especially following their training and induction process) only to be turned down without being given a thorough explanation left me feeling completely disregarded.
