Haskell online test helps tech recruiters & hiring managers to assess the programming skills of the Haskell engineer before hiring. This test has helped our customers reduce technical screening time by up to 85%.

Test Summary

Haskell programming skills test helps to screen the candidates who possess traits as follows:

Clear vision of understanding Recursive functions
Excellent knowledge of Compiler
Good hand-on experience with Functions
Strong understanding and knowledge of Runtime system
Understanding of High Order functions

Assessing candidates with our online test is secure and reliable. You can use our role-based access control feature to restrict system access based on the roles of individual users within the recruiting team. Features like window violation and webcam proctoring help detect cheating during the test.

This assessment includes innovative AI-LogicBox to assess a candidate's practical coding skills in a fun & quick way.

Topics Covered

Recursive functions

Haskell online test helps recruiters to understand the candidate’s knowledge of solving a particular problem by calling a function that repeats or uses its own previous term to calculate subsequent terms and thus forms a sequence of terms.

Functions

This test aids the recruiters in understanding the self contained modules of code that accomplish a specific task.

Runtime system

This Haskell programming skills test help you find out candidate’s awareness about an engine that translates a given programming language or languages into machine code.

High order functions

With iMocha’s pre-hire assessment you get an idea of a function that takes other functions as arguments or returns a function as result.

Compiler

This test lets you check the understanding of a computer program that translates computer code written in one programming language into another language.

Q 2. You are given a list for which you have to define a logic that returns all possible ways of inserting a new element into the list. Which of the following is the correct code for implementing the mentioned logic using a variable "n"?

interleave :: n -> [n] -> [[n]]
interleave x [] = [[x]]
interleave x (y:ys) = (x:y:ys) : map (y:) (interleave x ys)

interleave :: n -> [n] -> [[n]]
interleave x [] = [[x]]
interleave x (y::ys) = (x:y:ys) : map (y:) (interleave x ys)

interleave : n -> [n] - [[n]]
interleave x [] = [[x]]
interleave x (y::ys) = (x:y:ys) : map (y:) (interleave x ys)

interleave :: n -> [n] -> [[n]]
interleave x [] = [[x]]
interleave x (y:ys) = (x::y::ys) : map (y:) (interleave x ys)
