Haskell Interview Questions
In today's tough competition it's quite difficult to clear any interview. Haskell is one of the advanced programming languages, which provide easy integration with other languages, built-in concurrency, and rich libraries. It is perfectly suited for data analysis and proprietary business logic, enhancing current software with correct codification and scalability and performance.
There are various Haskell jobs in the market but to get selected in the job you need to clear the interview. Questions difficulty level can be different for fresher and experienced one. Freshers may get easy and simple questions whereas experienced candidates have to go through higher-level questions. So whether you are experienced or fresher, you need to prepare for the interview.
Having an interview with Haskell programming and thinking about the questions, which can be asked by you during the interview, come on we are here to sort out this issue for you. Go through below given questions, which might help you during the interview.
Haskell Interview Questions
1) Define Haskell?
2) In which language is Haskell written?
- Runtime: a combination of C, assembly, and C
- Compiler: Haskell
- Libraries: Haskell and some of C, a little assembly.
3) Define list? What are the ways to create a list in Haskell?
Usage of square brackets can create a list in Haskell with commas, which separates the list’s values. There are only four functions, which are normally required, but because lists are so widely used in Haskell programs, the prelude provides various another functions also.
4) State the key features of Haskell programming Language?
- Lazy evaluation
- Statically Typed
- Type inference
- Purely functional
- Concurrent
Haskell is completely functional language, or another term would be mathematical which means that functions have no side effects. With different features, this language provides functional programming, which offers extreme small and compact method for coding programs.
5) What is functional programming?
6) Differentiate between Functional vs. imperative Programming languages?
7) What do you mean by higher-order functions?
8) How to import a module in Haskell?
- Import the functions, which you need: The first thing, which makes your import clearer, is to specify which functions you want to import. The biggest provocation is only to write down the module name in the import. Once you have built a Haskell program of even modest size, then you will surely appreciate the importance of the import section of any source file.
- Qualifying Imports: After specifying the functions, which you need to import then move on the next way to clarify your imports is to use the qualified keywords. This clearly means that you should prefix every function you use from this module by the name assigned to the module.
- Organizing your imports: After qualifying imports, then next step is to organize the internal imports from external ones. So which means two list needs to create in the first list will consist of built-in-packages, and 2nd list has modules that are in the codebase itself.
- Creating the list easy to read -: At last you want to make it easy to read your import list. Write your list in alphabetical order, which helps people find the right module in the list.
9) What do you mean by Lambdas in Haskell?
10) What do you mean by Functor Class in Haskell?
