Assessment days (also called assessment centres) allow companies to assess candidates over an extended period of time, whilst offering candidates the chance to find out about an employer in greater detail. An assessment day also usually provides an opportunity for a candidate to meet with current employees at a firm. Assessment days can be long, time consuming and highly mentally demanding.
What is an Assessment Day?
An "assessment day" is an important part of the recruitment process for many graduate employers. As the name suggests, it is a period of extended assessment that usually lasts for the best part of a day, and occasionally, two, or even three days).
Generally speaking, the more prestigious the employer, the longer the assessment day will last for. An assessment day for an investment bank, such as Barclays Capital (BarCap), will usually last for two days and include an overnight stay. The assessment day for a retailer, such as Aldi will usually last for just one day, or even an afternoon.
A well structured assessment day is generally considered to be amongst the fairest and most objective means of selecting employees for jobs, particularly graduate jobs. This is because they give a number of different interviewers a chance to assess candidates over an extended period of time, enabling assessors to see what you can do, rather than what you say you can do, in a wide variety of situations.
Where do Assessment Days take place?
Assessment days are usually take place at employer's offices, although some firms use third party organisations to run their assessment days. For two and three day assessment days, some employers use hotels to run their assessment activities, hiring function rooms and paying for rooms and meals for candidates.
What happens at an Assessment Day?
Assessment days require you to participate in a number of individual and group exercises. The exact tasks involved are designed to replicate the demands of the specific job you have applied for. Assessment days usually comprise a mixture of: interviews (including competency based interviews and partner interviews), case studies, aptitude tests (such as verbal and numerical reasoning), personality tests, group exercises, role plays and presentations (both group and individual). Candidates are also usually given a tour of company offices during an assessment day and several opportunities to meet with, and talk to, current employees.
How to behave at an Assessment Day
Candidates should be assertive, enthusiastic and co-operative at an assessment day. An assessment day is not a competition; teamwork is key if you want to do well. Be friendly, polite and supportive to other candidates. Assessors are looking for competitive people who can work well with others, not just competitive people.

Hi Guys,
I went for my AC recently for a graduate position. so I just thought it would good to share my knowledge of what happened to help you guys. Mine lasted the whole day and consisted of the following exercises:
Group exercise Numeracy test Role play exercise Fast track ability test Interveiw
In the group exercise, the whole group was given different sets of proposals to look over and we had time to prepare notes on it. Then we had to present our information to the rest of the group (not in terms of a full on presentation but telling everyone about your proposal ie good points, bad points). Then you are given time as a group to decide which proposal you should go for. This is pretty straight forward and you need to think about what assesors are looking for. For example, everytime the group agreed on a decision, I would summarise it and ask if everyone in the group is happy. I also asked quieter members of the group if they were happy with the decisions made. Its not all about being the loudest person, but listening to others ideas, and if you agree with it or disagree, say so and why. also keeping an eye on the time and making sure that the group sticks to time is also key.
The numeracy test was pretty straightforward, its not hard at all and im crap at maths so you should be fine, just keeping practising, but also keep your eye on the time, kos it tends to pass really quickly. You dont get a warning if there is 5 mins to go so its pretty much up to you to be your own timekeeper.
The Fasttrack ability test is a timed exercise where you different sets of card with information on it and from this ou have to decipher a pattern and fill in missing bits of information on other cards. First couple of exercises was ok but i found it really hard towards the end. Im not sure if this is something that you can practise because I have never seen anything like this before!
Th role play exercise involved a scenario where you are working as a team and someone who you have been working with, is not producing the usually high standard of work you normally produce. You get given a brief about your role, the team you work in and also different sets of information in the form of emails. You then get given time to make notes and prepare a plan to bring in with you to the role play exercise which lasts 20 mins. This is where an actor comes in pretending to be the collegue and you have to extract some agreement from them by the end of the meeting. As well as being sympathetic, in terms of asking them if everything is ok in their personal and professional life, you also have to be firm where you need to be, for example, letting them know that the project you are working on is important. It also very good to schedule a time in the future where you will assess their progress again. There is loads of stuff on the web on how to prepare for role play exercises so dont worry about this.
The interveiw was very straight forward, no grilling questions just standard questions like why rbs, y the role and also some basic competency questions.
And thats it. I hope this helps guys, my best advice would be to prepare, after speaking to some of the other graduates, who were there, the advantage that you can have is by preparing. Research techniques that can help you to do well in group exercises and in role plays and keep practising your numeracy tests and you will do fine.
Good luck to all of you.
