Too many.
They proudly say they compete with big consulting firms and have high level standards. To be honest Wavestone do not play in the same league and never will. As they do not have/win enough projects for their consultants in the UK (weird for an alleged competitor of MBB and Big 4), they send them to their Paris office. They present it as "a development opportunity" to learn from their main office...but don't be a fool.
Regarding the management:
I was first pleased as it seems they showed eagerness and enthusiasm. Soon, I was disillusioned. I realised that their 2021 strategic vision is nothing but smoke and mirrors. Many employees resigned since the acquisition and many others will follow this trend in the future.
Also, the management and your career development manager won't give you the support you need and won't help you achieving your career goals. For staffing purposes, they will send you on any projects, anywhere, regardless your skills and aspirations. Are you Specialised in digital workspace? Let's send you on a cyber security project!
Some people of the management are disrespectful and demeaning to the staff. Many of them lack of vision. They kept the worst from Solucom. Let's see at the anniversary of Xceed acquisition who is still part of the new wavestone.. It might be enlightening.
Another surprising (and bad) thing is that they sell their consultants as experts but if you scratch the surface, you will quickly realise they aren't. Imagine sending on a client site a so-called IT architecture or cybersecurity consultant that actually knows nothing...
the firm has a toxic environment swamped in politics. Any ambition or eagerness to change is nipped in the bud.
Last point: there is a lack of transparency and equality regarding salaries, pay rises and promotions.. I am sure the acquisition only reinforces this disparity..
