Product Perfect

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+ app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in ABCL/c+ application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

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 are the primitive data types in ABCL/c+?

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

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.

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; }'.

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

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

Can the candidate work well in a team?

Next 20 minutes

Specific ABCL/c+ development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

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.

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; }'.

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

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

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.

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.

Oops! Something went wrong while submitting the form.

At this point, a skilled ABCL/c+ engineer should demonstrate strong problem-solving abilities, proficiency in ABCL/c+ programming language, and knowledge of software development methodologies. Red flags include lack of hands-on experience, inability to articulate complex concepts, or unfamiliarity with standard coding practices.

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.

Wrap-up questions

Final candidate for ABCL/c+ Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle ABCL/c+ application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

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.

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.

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; }'.
