I worked at Opus Energy full-time
Good pay for what the role actually was, my managers and colleagues were fantastic, there were lots of opportunities to progress within the company, and it was the only call centre that I've ever worked in where I felt genuinely valued and respected as an individual by all of the management, and wasn't just viewed as a number, or as a tool to keep their stats afloat. Vikki Sanger is also one of the best managers that you could ever ask for, and I've never had one since that could top her.
The training wasn't amazing, but that's because my time were the first ones in to the Cardiff office, so we were basically the guinea pigs.
I applied online. The process took 3+ weeks. I interviewed at Opus Energy (Northampton, England).
Submitted CV and was contacted next day. Had a phone interview within a week and a second interview the next day. Was told at the interview that I would hear an outcome (either positive or negative) within 3 days. I followed up after 2 weeks, having not heard either way, to be told that the feedback 'must have fallen through the net due to annual leave'. The casual lack of concern for following through on the promised action did not leave a good impression.
