1. Let's introduce .NET development to you

• Origin story: .NET was launched in Feb 2002 by Microsoft, originally called NGWS (Next Generation Web Services).


• Widely popular: According to Daxx, there are about 6 million .NET developers in the world and since it is adopted by most of the tech companies in the world, the demand for .NET developers is ever rising.


• Top companies using .NET: Companies like Dell, Accenture, TCS, and HCL use .NET.



2. Why is .NET widespread?

• Large Library: .NET has a large collection of predefined class libraries that has support for simple and complex data structures. You can rely on the work of hundreds of other developers and pull already-written code into your own programs.
• Environment: .NET is a free platform that provides a programming environment for most software development phases. Best for the companies that look for features like web-based services, desktop software, and cloud infrastructure support.



3. What are the tools used by .NET developers?

The following are some of the tools used by .NET developers at various stages of development:

1. .NET Reflector
It is a decompiler, disassembler, and static analyzer for the .NET framework and helps developers understand and debug their .NET code.

2. Stackify Prefix
This is a lightweight code profiler tool for .NET developers which allows developers to retrieve performance data. It can also troubleshoot web requests that are slow and find slow queries.

3. Postman
It is an open-source collaboration platform for testing APIs, and an HTTP client used across the world for designing, developing, and testing APIs.

4. SonarQube
SonarQube is an open-source static code review tool that helps in maintaining the .NET code quality by performing automatic reviews with static analysis of code to detect bugs, code smells on the code.

5. PerfCollect and PerfView
These tools are used to trace the performance of the machine to figure out the root cause. PerfView is a free performance-analysis tool that helps isolate CPU and memory-related performance issues.PerfCollect is a bash script that uses Linux Trace Toolkit used to collect events written from the runtime.




4. Writing the Job Description to hire a .NET developer

Below are some key points that we at Flexiple have learned through trial and error - a process of filtering through over 15,000 developers.

• Years of software development experience: Be specific about the technology you’re looking for and the number of years of experience needed. A proxy to years of experience can be the number of production-level apps worked on.


• Expertise in a specific language: All languages have their peculiarities and nuances. While good .NET developers can pick up other languages, it’s a plus point to hire a developer who already has expertise in it.


• Type of products built in the past: You can filter out applications based on the candidate’s past work if you want someone who has a fair idea about how things work in a product like yours.


• Exposure to specific industries:  Developers who have built products in certain industries will already know key aspects of laying the foundation for a great product and will be able to predict possible problems.


• Experience working remotely: Hiring someone who has worked remotely in the past is an added benefit as they have front-hand experience of everything right from how the contracts work to communication and from timelines to deliverables.


• Strong communication: An essential thing to look at when hiring a freelancer is excellent communication skills. Since all the interaction happens online, a freelancer needs to be able to seek to understand and be direct in their language.

5. Interview Questions for hiring a .NET developer

Now that you have made a quality JD, it can still be tricky to evaluate the skills of your applicants. To help you with that, we have created a pool of questions that a good .NET developer should be comfortable with. You can check out some related interview questions on this page.
It is important to note that the ability to answer these questions doesn't imply that you have a top quality candidate. But it definitely is a big step in that direction.

To help you navigate through these questions, we’ve categorized the interview questions in 3 parts:


A. Basic concepts: Includes all basic concepts used across languages. This section will give you an understanding of how strong their programming foundation is.

B. Advanced concepts: Includes all concepts that someone with higher expertise should know.

C. DS/Algorithm questions: To test the logical capability of the candidate.




A. Basic concepts

B. Advanced concepts

C. Data Structure/ Algorithm

var x = 10;
var y = 5;
var z = 3;
if (x / y / z)
     document.write("hi");
else
    document.write("hello");

The answer is A, the floating-point division in JS returns a non zero value = 0.66 which evaluates to 
true and outputs ‘hi’.
