Recently Mastercard visited our campus for SDE intern recruitment and below is my experience 🙂 There were overall 3 rounds conducted. Online coding test. Technical round 1 Technical round 2 + HR

1.There was a string given consisting of words separated by white space, we have to return the pair number of in each word where a pair of two neighbor characters is valid if they follow a lexicographical order.

2.Bob wants to purchase N pens and he has prepared a list of shops that sell the pens. Each shop charges a different price per pen and has a limited quantity available in stock. Along with the price of pens each shop charges fixed delivery fees irrespective of how many pens are brought. Help Bob to get N pens as cheaply as possible. (It was a medium DP problem similar to the knapsack problem).
