Its good to see you are casting you net wide and networking your way. 10/10 for that!
Its not a tech consulting firm anymore. The breadth and scale of Accenture has made it one of the most sought after companies in the recent 5-10 years. It now plays in Strategy, Digital Transformation, Marketing etc. Just check out Gartner/Forrester rating and Accenture pretty much leads all qudrants even beating MBB in Digital Transformation expertise for example (https://www.accenture.com/us-en/insights/consulting/forrester-digital-business-transformation) So dont worry about.
Note that Accenture Strategy is not at the same level as MBB, so you need to play the wider Accenture brand in your story i.e Accenture offers exposure to all those areas where MBB dont play giving you more experience in e2e business problems.
Without getting direct feedback from HR/Hiring Manager we can only speculate:
- No current demand to match your skills
- Not enough budget to hire you
- Impact of COVID, in UK its still very tough at the moment; plus London office is hyper competitive
- Hiring freeze or exceptional only hiring in many places
- Visa considerations- I believe US has extended ban till end Mar and UK has now moved to points based systems
Path to MBB
Think about making most of the Accenture role for however long you intend you stay with them. Make a plan and work with the managers etc to get involved in the right projects. CN supports pretty much US/Europe clients, so you will get exposed to that geogprahy nonetheless but be mindful that due to COVID projects could be difficult to get.
Make sure your CV, cover letter and career story are all slick and convincing. Keep trying and you will hit home run. Its a matter of time but be patient, specially as COVID continues to cause damage.
