ABCL/c+ Developer Hiring Guide

Hiring Guide for ABCL/c+ Engineers

Ask the right questions to secure the right ABCL/c+ talent among an increasingly shrinking pool of talent.

ABCL/c++ is a dialect of the programming language Common Lisp. It was developed by Kent Beck in the early 1990s at Xerox PARC. ABCL/c++ is designed to be a "better C++", combining the features of C++ with the expressiveness of Lisp. ABCL/c++ is open source software and is available under the MIT license.

First 20 minutes

General ABCL/c+ knowledge and experience

The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.

What are the different types of loops in ABCL/c+?

ABCL/c+ supports several types of loops including 'for', 'while', and 'do-while' loops.

How would you use a conditional statement in ABCL/c+?

In ABCL/c+, conditional statements are used with the 'if' keyword. For example, 'if (x > y) { return x; } else { return y; }'.

Describe the difference between local and global variables in ABCL/c+.

Local variables are declared within a function and can only be accessed within that function. Global variables, on the other hand, are declared outside all functions and can be accessed by any function within the program.

What are the primitive data types in ABCL/c+?

The primitive data types in ABCL/c+ include integers, floats, characters, and booleans.

How would you declare a variable in ABCL/c+?

To declare a variable in ABCL/c+, you would use the 'let' keyword followed by the variable name and its value. For example, 'let x = 10;'.

What youre looking for early-on

Does the candidate show a willingness to learn and adapt?

The field of software development is constantly evolving. A good candidate should be open to learning new technologies and adapting to changes.

Is the candidate able to work under pressure and meet deadlines?

In a fast-paced development environment, the ability to work under pressure and meet deadlines is important. The candidate should be able to manage their time effectively.

Can the candidate work well in a team?

Software development often involves working in teams. The candidate should be able to communicate effectively and collaborate with others.

Is the candidate able to solve problems effectively?

Problem-solving is a key skill for any developer. The candidate should be able to demonstrate their ability to think critically and solve complex problems.

Has the candidate worked on relevant projects?

Past experience on relevant projects can be a good indicator of the candidate's ability to perform in the role. It shows they have practical experience and can apply their skills effectively.

Does the candidate have a solid understanding of ABCL/c+?

This is crucial because the job role is specifically for an ABCL/c+ developer. The candidate should have a deep understanding of the language and its nuances.

Next 20 minutes

Specific ABCL/c+ development questions

The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.

How would you handle exceptions in ABCL/c+?

In ABCL/c+, exceptions are handled using the 'try-catch' construct. The 'try' block contains the code that may throw an exception, and the 'catch' block contains the code to handle the exception.

Describe the difference between positional parameters and keyword parameters in ABCL/c+.

Positional parameters are identified by their position in the function call. Keyword parameters, on the other hand, are identified by their name and can be specified in any order in the function call.

What are the different types of function parameters in ABCL/c+?

ABCL/c+ supports two types of function parameters: positional parameters and keyword parameters.

How would you define a function in ABCL/c+?

In ABCL/c+, a function is defined using the 'defun' keyword followed by the function name, parameters, and body. For example, 'defun add(x, y) { return x + y; }'.

Describe the difference between a 'while' loop and a 'do-while' loop in ABCL/c+.

A 'while' loop checks the condition before executing the loop body. A 'do-while' loop, on the other hand, executes the loop body first and then checks the condition.

The ideal back-end app developer

What you’re looking to see on the ABCL/c+ engineer at this point.

The candidate should demonstrate proficiency in ABCL/c+ language, problem-solving skills, and strong communication abilities. Red flags would include lack of specific technical knowledge, inability to articulate complex concepts, and a lack of relevant project experience.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with ABCL/c+.

What does the following ABCL/c+ code do?

int main() { int a = 10; int b = 20; int c = a + b; printf('%d', c); return 0; }

This code declares two integer variables 'a' and 'b', assigns them the values 10 and 20 respectively, adds them together and assigns the result to the variable 'c'. It then prints the value of 'c', which will be 30.

What will be the output of the following ABCL/c+ code?

int main() { int i; for(i=0; i<5; i++) { printf('%d ', i); } return 0; }

This code will print the numbers 0 to 4, each followed by a space. The 'for' loop iterates from 0 to 4, and on each iteration it prints the current value of 'i'.

What does the following ABCL/c+ code do?

int main() { int arr[5] = {1, 2, 3, 4, 5}; int i; for(i=0; i<5; i++) { printf('%d ', arr[i]); } return 0; }

This code declares an array of 5 integers and initializes it with the values 1 to 5. It then iterates over the array using a 'for' loop and prints each element of the array.

What does the following ABCL/c+ code do?

int main() { int a = 0; #pragma omp parallel num_threads(4) { a++; } printf('%d', a); return 0; }

This code declares an integer variable 'a' and initializes it with 0. It then increments 'a' in a parallel region executed by 4 threads. The final value of 'a' depends on the timing of the threads and is therefore indeterminate.

What does the following ABCL/c+ code do?

class MyClass { public: int x; MyClass(int val) : x(val) {} }; int main() { MyClass obj(10); printf('%d', obj.x); return 0; }

This code defines a class 'MyClass' with a public integer member 'x' and a constructor that initializes 'x' with a given value. It then creates an object of 'MyClass', initializes 'x' with 10, and prints the value of 'x'.

What will be the output of the following ABCL/c+ code?

int main() { int a = 10; int b = 20; int c = a > b ? a : b; printf('%d', c); return 0; }

This code declares two integer variables 'a' and 'b', assigns them the values 10 and 20 respectively, and assigns the larger of the two values to the variable 'c'. It then prints the value of 'c', which will be 20.

Wrap-up questions

Final candidate for ABCL/c+ role questions

The final few interview questions for a ABCL/c+ candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.

Describe the difference between an instance member and a static member in ABCL/c+.

Instance members belong to an instance of a class and each instance has its own copy of these members. Static members, on the other hand, belong to the class itself and there is only one copy of these members shared by all instances of the class.

What are the different types of class members in ABCL/c+?

ABCL/c+ supports two types of class members: instance members and static members.

How would you create a class in ABCL/c+?

In ABCL/c+, a class is created using the 'class' keyword followed by the class name and body. For example, 'class MyClass { int x; int y; }'.

Describe the difference between a checked exception and an unchecked exception in ABCL/c+.

Checked exceptions are exceptions that must be declared in the function signature or caught within the function. Unchecked exceptions, on the other hand, are exceptions that do not need to be declared or caught.

What are the different types of exceptions in ABCL/c+?

ABCL/c+ supports several types of exceptions including arithmetic exceptions, null pointer exceptions, and array index out of bounds exceptions.
