In-depth questions
These are more technical questions that may require you to think about how to solve a problem. Interviewers like answers that are clear and easy to understand, so you might want to use a human approach and voice when you summarise your answer. Here is a list of 10 common detailed questions you might be asked during an interview:
- How might you use the “DataRelation” class?
- How do most people get into Ado.net?
- What happens in a partial class? What are the names and rules for it?
- What is the main way to control how connections are shared?
- When does it make sense to bind a “DataGridView” control?
- How could you use the “ExecuteNonQuery” object?
- What are the three most-used commands in Ado.net?
- What are some of the classes in the namespace that are used the most?
- What’s the difference between a connected framework and a disconnected framework in Ado.net?
- How do you use the different levels of access to Ado.net? Which is better?
Sample interview questions and how to answer them
You might want to practise with someone else as you get ready for the interview. Depending on the question, this might make you look more sure of your answers and ready to give them more quickly. Here are some examples of how to answer five common interview questions:
In the context of the ACID property structure, what does “atomicity” mean?
This question is very technical and is meant to see how well you understand how useful Ado.net is. You can show how well you know the Ado.net structure and how flexible you are with it by answering more specific questions. If you don’t know the answers to these kinds of very technical questions, you could just say that you don’t know but plan to learn more about the subject.
Example: “In the ACID property structure framework for Ado.net, I would say that the best definition of atomicity is the guarantee of an all-or-none rule for your database. This helps keep the entries the same and makes it less likely that you’ll make a mistake.”
2. Talk about the different layers of Ado.net.
Even though these are technical questions, they are meant to show how flexible your experience and theoretical knowledge are. People may ask you these kinds of questions more often if you have a traditional undergraduate degree or a lot of work experience. Answer as simply as you can so that the person interviewing you can understand you.
“Ado.net has three main layers: the presentation layer, the business logic layer, and the database access layer.” All of them help the organisation reach different goals and show different levels.
What is the difference between data sets that are typed and those that aren’t?
Most of the time, organisations want data to be shown in a certain way. These kinds of questions can help the interviewer figure out how much you know about different kinds of entries and how to handle them. Consider giving your answer more context and, if you can, pointing out the benefits of your choice to add value.
Example: “There are major differences between typed and untyped data sets. Users can use names that wouldn’t be on a dataset that wasn’t typed. Data sets that haven’t been typed use columns and numbers instead of names, and they serve different purposes.
How does the concept of pooling change the way connections are shared?
This question shows how good you are at programming in the real world. You’ll also have to explain this to someone who may not understand it as well as you do. Think about answering this question step by step, as if you were teaching them. This will make sure that your answer is clear.
Example: “The pooling construct is an important part of keeping track of and controlling how connection pooling works. It has to do with how well connection pooling works, and if the value is set to “True,” it can get requested connections.
5. What’s the difference between ExecuteScaler and ExecutenonQuery?
This is a question that can show hiring managers that you pay attention to the details. Code is hard to understand, and it takes a trained eye to find problems and make solutions. When answering such detailed questions, you might want to be as thorough as possible so that your boss can see how much you know about the topic.
Example: “ExecuteScaler is very different from ExecutenonQuery in a very important way. With ExecuteScalar, you can get a single value from a returned dataset. With ExecutenonQuery, you can get more than one value from a single data set. You can’t use one instead of the other.”
