You will be doing different work.
I believe the Turnardound and Restructuring to be more challenging and broader function. It will mostly be about finding how to optimize the financial structure of the company (you may want to check if they do operational restructuring as well), and then supporting the negotiations with lenders & investors.
Deals should be mostly about performing financial due dilligence work ("re-doing" the accounts to better reflect the financial situation of the company and pinpointing the key risks).
EY-P is a better brand, but beware that this role is not a strategy role. Basically EY's T&R team was moved under the EY-P brand, which probably has the better value proposition (for customers) whenever work meets the Corporate Finance - Corporate Strategy intersection.
If you mention you did like the manager (i.e., a single one, not the managers). If it is a big office, you should weight on the culture, not on a specific manager. If it is a small office, then a single person will have a lot of impact on your experience.
Finally, did you like doing deals advisory? Or would you rather do something a bit different?
I've worked for EY-P before, so feel free to reach out if you want to further discuss.
Thank you! This was helpful. I talked again with some of the people at EY-P and liked the culture there better. I think work will be more interesting there too (Not to say Deals was not interesting. I enjoyed my time at deals advisory, due diligence was certainly interesting, although we only did market entry assessment.), so I've decided to go to EY-P. The deals strategy team at the office I applied to was really small, 13 people myself included. But I liked most of the people there (didn't really get to interact much with 2 of them). I really liked manager in charge of me as an intern, he was really nice and encouraging. But again, I've decided to go to EY-P because after speaking with several people there including the partners, I found that I liked the culture there more. The partner who was my final round interviewer was really nice too! And she shared a lot about her experiences with me and was really keen to get me on board. Again, thanks for your comprehensive answer! :)
Happy to know I was helpful, and happy for you! Also feel free to reach out at anytime if you just want some tips on how to be successful or to further understand the company.
