This year's assessment centre for graduates who are interested in joining the electricity distribution firm was different to ones candidates may have experienced elsewhere.
The candidates were given three team exercises to do that were designed around real jobs within the electricity distribution company. They would have to do those jobs if they worked for the company, therefore giving both UK Power Networks and its prospective employees the chance to really see if they were suitable for one another.
Usually assessment centres at other companies offering graduate courses involve standard exercises and not the actual work a graduate would be expected to carry out for the company if they were successful.
Part of the assessment centre was designed by commercial graduate Carina Correia and current engineering graduate trainee Daniel Steele.
Audrey Bevan, recruitment adviser for UK Power Networks, said: "It is nice that it's actually gone full circle with former and current graduates having a hand in designing our recruitment process.
"We are quite unique in the way we have designed it this year. The more information applicants have, the better they are able to make an informed decision."
Out of 54 candidates, the list has now been whittled down to 20 interviewees to carry on to the next part of the process.
UK Power Networks employs about 10 graduates each year as part of its Graduate Engineering Programme and Business and Commercial Management Graduate Programme.
Both courses take three years to complete, incorporating a 12-month training programme followed by two, one-year supported placements.
UK Power Networks distributes electricity to about eight million homes and businesses in the East, London and the South East. Its engineers maintain and repair thousands of miles of underground electricity cables and overhead power lines as well as substations.
