The interview process consists of 4 rounds:

• 2 Technical rounds
• 1 Managerial round
• 1 HR round

In the first two rounds, they asked about OOP basics (explain the 4 pillars of OOP), jQuery, and C# concepts like the dynamic property and extension methods. They also covered SQL queries such as Joins and GroupBy, which you can revisit from w3schools.com.

More questions came from WCF (A, B, C concepts), different contracts in WCF, and different HTTP protocols and their differences.

In the third round (Manager Round), the focus was more on planning, scheduling, and prioritizing your tasks. They basically wanted to know if you are a good planner who can be trusted by the team.

The final round was the HR round and consisted more on salary negotiations and perks at Dell.

Hope this helps someone appearing for similar interviews at Dell or anywhere else. All the best.
