In addition to the feedback posted already, I would consider removing the Interest and Skills section, as in my opinion it does not really add anything relevant to your application (e.g. you are typically required to submit your language skills in the electronic application form of most consulting firms anyway, and proficiency in Excel, Powerpoint etc. is not a formal requirement, at least for MBB and Tier2).
Instead, I would fill the space by elaborating on several points on your CV:
- This FinTech startup sounds amazing, maybe write 2-3 more bullets on what the startup was about and what you exactly did and achieved
- Have you done any internships during your studies? If so, add them in the Professional Background section
- Did anything else interesting happen during your studies? Research/teaching assistantship positions? Scholarships? Awards? If you know your class rank and it is at least top 5-10%, include it (even more important than the GPA itself)
