I'm not going to run through all the cons, but will highlight a few facts. To be honest I don't really need to say that much, the proof is there for itself.
Firstly just look at the turnover! 20 employees, including 2 managers in the past 18 months, and that's just the BDM sales team, the office must be nearly in triple digits.
You only need to find these former employees on LinkedIn and ask them about their experience. This way you will be going in with your eyes wide open.
You can also Google their sister company and see the BBC articles showing their wrong doing.
If you do decide to take up employment as a BDM; at interview stage or when working directly - if anything is promised to you or guarantees or assurances given in respect of appointments/ commissions/ bonus etc that those people need to ensure to obtain same clearly in writing from the company.
Also make sure to look at all the negative reviews here on Glassdoor everything in them is true. You will start to see similar issues mentioned in them.
One of the more familiar issues is that the company is rife with favouritism.
Figures from those who are spoon fed all the good appointments from the office will be shown to prospective new sales staff as being what they can earn - they can’t earn it and they should ask to see the full sales team figures and question why such a huge difference in appointments allocated and subsequently targets achieved and money earned.
New employees need to understand that they will be watching a number of those spoonfed employees making circa 300k while being compared to those people and questioned why they aren’t achieving the same - it’s very simple - new employees will not get looked after in the same way instead you will be asked to make up the deficit with sales from self generated meetings a feat that nobody is doing, so make sure to ask to see reports for the percentage of self gen sales those spoon fed employees are achieving or anyone in the company for that fact.
