Hiring guide for Data/BASIC+++. Engineers

Data/BASIC+++. Developer Hiring Guide

BASIC+++ is a computer software programming language, developed as an enhanced version of the original BASIC language. Introduced in 1964 by John Kemeny and Thomas Kurtz at Dartmouth College, BASIC was designed to simplify computer programming for non-technical users. The '+++' in BASIC+++ signifies advancements and improvements over the standard BASIC language, enhancing functionality and ease of use. These enhancements include object-oriented features which were not present in the original version. As a versatile and user-friendly language, BASIC+++ continues to be relevant in modern computing environments.

First 20 minutes

General Data/BASIC+++. app knowledge and experience

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

How would you describe the role of a Data/BASIC+++ developer?
A Data/BASIC+++ developer is responsible for designing, developing, and implementing applications using the BASIC+++ programming language. They also handle data management tasks, including data extraction, transformation, and loading (ETL), data modeling, and data analysis.
What are some of the key features of BASIC+++ programming language?
BASIC+++ is a high-level programming language that is easy to learn and use. It supports structured programming, has a rich set of built-in functions, and allows for the creation of complex data structures. It also supports object-oriented programming.
Describe the difference between a local and a global variable in BASIC+++.
A local variable is declared within a procedure and can only be accessed within that procedure. A global variable, on the other hand, is declared outside all procedures and can be accessed by any procedure within the program.
How would you handle errors in BASIC+++?
BASIC+++ provides several error handling mechanisms. The most common one is the use of the ON ERROR statement, which allows the programmer to specify what action to take when an error occurs.
What are the different data types supported by BASIC+++?
BASIC+++ supports several data types, including integer, floating-point, string, boolean, date/time, and complex data types like arrays and objects.

Next 20 minutes

Specific Data/BASIC+++. 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 function and a procedure in BASIC+++.
A function is a block of code that performs a specific task and returns a value, while a procedure is a block of code that performs a specific task but does not return a value.
How would you create a multidimensional array in BASIC+++?
In BASIC+++, you can create a multidimensional array by specifying multiple dimensions in the DIM statement. For example, DIM myArray(3, 3) creates a 3x3 array.
What are the different control structures available in BASIC+++?
BASIC+++ supports several control structures, including IF...THEN...ELSE for conditional execution, FOR...NEXT and WHILE...WEND for loops, and SELECT CASE for multi-way branching.
Describe the difference between a static and a dynamic array in BASIC+++.
A static array has a fixed size that is determined at the time of declaration, while a dynamic array can change its size during program execution using the REDIM statement.
How would you handle file I/O operations in BASIC+++?
BASIC+++ provides several statements for file I/O operations, including OPEN for opening a file, CLOSE for closing a file, INPUT# and LINE INPUT# for reading from a file, and PRINT# for writing to a file.

The ideal back-end app developer

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

At this point, a skilled Data/BASIC+++. engineer should demonstrate strong problem-solving abilities, proficiency in Data/BASIC+++. 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 Data/BASIC+++..

What does the following BASIC++ code do?
PRINT "Hello, World!"
This code prints the string 'Hello, World!' to the console.
What will be the output of the following BASIC++ code?
x = 5
PRINT x * 2
The output will be 10. The code declares an integer variable 'x', assigns it the value 5, and then prints the result of 'x' multiplied by 2.
What does the following BASIC++ code do?
FOR i = 0 TO 5
arr(i) = i * 2
PRINT arr(3)
This code initializes an array of integers with 6 elements, assigns each element a value which is twice its index, and then prints the value of the fourth element in the array, which will be 6.
What does the following BASIC++ code do?
x = 5
PRINT y * 2
This code declares an integer variable 'x', assigns it the value 5, creates a new thread that runs the subroutine 'MyThread' with 'x' as its argument. The subroutine 'MyThread' prints the value of its argument multiplied by 2.

Wrap-up questions

Final candidate for Data/BASIC+++. 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 Data/BASIC+++. application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different ways to pass parameters to a procedure or a function in BASIC+++?
In BASIC+++, parameters can be passed by value, where a copy of the value is passed, or by reference, where a reference to the original variable is passed.
Describe the difference between sequential and random file access in BASIC+++.
In sequential file access, data is read or written in a sequential manner, from start to end. In random file access, data can be read or written at any position in the file.
How would you implement recursion in BASIC+++?
In BASIC+++, recursion can be implemented by having a procedure or a function call itself. Care must be taken to ensure that the recursion has a base case to prevent infinite recursion.
