How Morgan Stanley interviews Software Engineers
Morgan Stanley is a leading global investment bank hiring across banking, sales & trading, research, technology and wealth management. Its process is competitive and division-specific, balancing technical strength with behavioural and cultural fit.
For a Software Engineer specifically, Morgan Stanley pairs its standard assessment with a technical bar focused on data structures & algorithms, system design, a core language (e.g. python, java, go). Software engineering interviews test three things: can you code cleanly under time pressure, can you design systems that scale, and can you work in a team. The bar rises with seniority — juniors focus on coding fundamentals, while senior and staff candidates spend more time on architecture and influence.
