Pros
It's a Big 4 company so the branding is there. It may allow you better opportunities to find a slightly more senior role within industry if you're looking to use it as a springboard. It does have a global presence so you can reach out to other offices for information if needed. In addition, depending on the projecs, Deloitte is generally flexible if you need to work from home as long as it does not impact the project.
Cons
Inaccurate scoping and workbench measurement when selling projects. Lack of employee engagement and talent management, which is a norm in Singapore since employees do not get much benefits or protections by the government. Lack of transparency of salary scale and promotion criteria. Lack of respect for work-life balance. Hierarchical.
