Interviewing at WNS
What the process looks like, and what WNS is really testing for.
WNS interviews are a mix of screening and multiple technical evaluations. Across reported roles, you start with HR level screening, then move into technical assessments that focus on practical skills, followed by at least one case study presentation and an end-stage discussion with leadership or HR.
The topics data shows WNS heavily tests analytics and operational thinking through Excel and secondary research, plus finance and automation fundamentals through accounting concepts, journal entries, forecast modeling, and VBA. For programming and technical roles, SQL is prominent, and you should also expect Microsoft-centric stack signals like C# and ASP.NET, plus system design topics like design patterns.
Difficulty is mostly medium, with 29.2% easy, 57.5% medium, 12.3% hard, and 0.9% very hard. The provided candidate aggregate reports show an offer rate of 0.0%, so you should treat outcomes with caution and focus on doing well in the demonstrated skills and evidence of communication during the case and behavioral portions.
The most non-obvious pattern is that your loop can include both a case study presentation to senior leaders and additional technical evaluations that get more complex, so you need to be ready to explain your work clearly, not just compute answers.

Technical evaluations and/or case study presentation
