Common Cobol Developer Interview Questions

What inspired you to choose Cobol as your development language?

There are a few reasons why an interviewer might ask this question. First, they may be interested in knowing whether the Cobol Developer has a strong preference for Cobol or if they would be open to using other languages. Second, the interviewer may want to know if the Cobol Developer has a specific reason for choosing Cobol over other languages, such as its readability or its ability to handle large amounts of data. Finally, the interviewer may be interested in knowing if the Cobol Developer is familiar with other languages and how they compare to Cobol.

Example: “Cobol is one of the oldest high-level programming languages and has been in use for over 50 years. It is still used today in a variety of industries, including finance, insurance, and government. I was inspired to choose Cobol as my development language because of its long history and continued use in mission-critical applications. Cobol is a stable and robust language that is well suited for developing large-scale enterprise applications.”

What do you think sets Cobol apart from other languages?

There are a few reasons why an interviewer would ask this question:

1. To gauge the Cobol Developer's understanding of Cobol compared to other languages. It is important to know how a Cobol Developer views Cobol in relation to other languages because this can impact their development approach and the tooling they use.

2. To better understand the Cobol Developer's motivations for using Cobol. It is important to know why a Cobol Developer chooses to use Cobol over other languages because this can impact the development process and the end product.

3. To get a sense of the Cobol Developer's priorities when it comes to language features and tooling. It is important to know what a Cobol Developer values in a language because this can impact the development process and the end product.

Example: “There are a few things that set Cobol apart from other languages:

1. Cobol is designed for business applications. It is not suitable for general-purpose programming like C or Java.

2. Cobol is very verbose, which makes it easy to read and understand. This is beneficial for maintenance and debugging, but can make the code more difficult to write.

3. Cobol has a very strict syntax, which can be difficult to learn at first but ultimately makes the code more reliable.

4. Cobol is not widely used outside of business applications, so there is less of a community and support infrastructure around it compared to languages like C or Java.”

What do you think is the biggest advantage of Cobol?

Cobol is a very old programming language, and as such, it has been widely used in a variety of industries for many years. Its popularity means that there is a large pool of Cobol developers with a wide range of experience, which can be a big advantage when hiring for a project. Additionally, Cobol is a very stable language, which can be important for mission-critical applications.

Example: “There are many advantages of COBOL, but some of the most notable ones include its ease of use, portability, and scalability. COBOL is also one of the most widely used programming languages, with millions of lines of code written in it every year.”

How would you explain Cobol's syntax to someone who is unfamiliar with it?

Cobol's syntax is important to understand because it is a very old programming language and it is not commonly used anymore. However, it is still used in some legacy systems. Therefore, it is important for a Cobol Developer to be able to explain the syntax to someone who is not familiar with it.

Example: “Cobol's syntax is very simple and easy to understand. It is based on a fixed format, which means that every statement must start in a certain column and end in a certain column. This makes it easy to read and write Cobol programs.”

What do you think is the biggest challenge when working with Cobol?

There are a few possible reasons why an interviewer might ask this question:

1. To gauge the Cobol Developer's level of experience and expertise. If the Cobol Developer is relatively inexperienced, they may not be aware of some of the challenges that can arise when working with Cobol.

2. To see if the Cobol Developer is up-to-date on the latest challenges faced when working with Cobol. As technology evolves, new challenges always arise - it's important for developers to be aware of these so that they can stay ahead of the curve.

3. To get a sense of the Cobol Developer's problem-solving skills. By asking about the biggest challenge when working with Cobol, the interviewer can see how the Cobol Developer would handle a difficult situation. This can be helpful in determining whether or not the Cobol Developer is a good fit for the position.

Example: “There are a few challenges when working with Cobol. Firstly, it can be difficult to read and understand Cobol code due to its verbose and dense syntax. Secondly, Cobol is an old language and lacks many modern features and libraries that newer languages have. This can make development more difficult and time-consuming. Finally, there is a lack of skilled Cobol developers, which can make finding help and support difficult.”

What do you think would be the biggest advantage of using Cobol in development?

Cobol is a very old language, and as such, it has a lot of advantages over newer languages. It is very stable, and has been used in mission-critical applications for decades. It is also very portable, and can be run on a wide variety of platforms.

Example: “Cobol is a very old language, and as such has a lot of advantages over newer languages. For one, it is very stable and well-understood. There are few surprises when working with Cobol, and it is easy to find help when needed. Additionally, Cobol is very efficient in terms of both memory usage and execution time. It is also very portable, meaning that programs written in Cobol can run on many different platforms with few or no modifications.”

What are your thoughts on the future of Cobol?

An interviewer would ask this question to a Cobol Developer to get their opinion on the future of Cobol programming language. It is important to know the opinion of a Cobol Developer because they are the ones who use the language on a daily basis and have a better understanding of its capabilities.

Example: “There is no doubt that Cobol has been around for a long time and has been an important part of the computing industry. However, there is also no doubt that Cobol is facing some serious challenges in the current market.

One of the biggest challenges that Cobol faces is the fact that it is not a very popular language among developers. In fact, according to the TIOBE Index, Cobol ranks as the 50th most popular programming language. This means that there are very few developers who are interested in learning or working with Cobol.

Another challenge that Cobol faces is its lack of features compared to other languages. For example, Cobol does not support object-oriented programming (OOP), which is a major feature that many modern languages support. This lack of features makes it difficult for Cobol to compete with newer languages.

Finally, another challenge that Cobol faces is its declining use in the business world. Many businesses are moving away from using Cobol due to its high costs and lack of features. This decline in use could lead to a further decline in popularity for the language, which would make it even more difficult for Cobol to compete in the future.

Despite these challenges, there are still some reasons”

There are a few reasons why an interviewer might ask this question to a Cobol developer. First, it can give the interviewer some insight into the developer's thoughts on the future of Cobol. Second, it can help the interviewer gauge the developer's level of experience with Cobol. Finally, it can help the interviewer determine if the developer is interested in staying up-to-date on Cobol developments.

Example: “Cobol is a very old programming language, and it doesn't seem likely that it will continue to be popular in the future. It is not as widely used as it once was, and there are newer languages that are more suited for modern applications. However, Cobol does have its fans, and there are still many organizations that use it for mission-critical applications. It is likely that Cobol will continue to be used in some form for many years to come.”
