Hiring guide for JZX BASIC Engineers

JZX BASIC Developer Hiring Guide

JZX BASIC is a structured, BASIC-like programming language developed by Japanese computer scientist Jun-ichi Nishimura in 1978. It was first implemented on the NEC PC-8001 home computer. JZX BASIC was later ported to other Japanese personal computers, including the NEC PC-8801 and PC-9801. The language is still in use today, and is supported by a number of compilers and interpreters.

First 20 minutes

General JZX BASIC app knowledge and experience

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

How would you start a new JZX BASIC program?
You would start a new JZX BASIC program by typing 'NEW' in the JZX BASIC command line interface.
What are the key data types supported by JZX BASIC?
The key data types supported by JZX BASIC are integer, floating point, string, and array.
How would you create a loop in JZX BASIC?
You can create a loop in JZX BASIC using the 'FOR' and 'NEXT' keywords. For example: 'FOR i=1 TO 10: PRINT i: NEXT i'.
Describe the difference between a subroutine and a function in JZX BASIC.
A subroutine is a set of instructions that perform a specific task and can be called from anywhere in the program. A function, on the other hand, is similar to a subroutine but can return a value.
What are the uses of the 'DIM' statement in JZX BASIC?
The 'DIM' statement is used in JZX BASIC to declare an array or a string variable with a specified size.

Next 20 minutes

Specific JZX 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.

How would you handle errors in JZX BASIC?
You can handle errors in JZX BASIC using the 'ON ERROR' statement. This allows you to specify a line of code to be executed when an error occurs.
What is the purpose of the 'DATA' statement in JZX BASIC?
The 'DATA' statement is used in JZX BASIC to store constant values that can be read later by the 'READ' statement.
Explain the difference between 'GOSUB' and 'GOTO' in JZX BASIC.
'GOSUB' is used to call a subroutine, after which control returns to the command following the 'GOSUB'. 'GOTO', on the other hand, transfers control to a specified line number or label, but does not return control.
How would you read and process data from an array in JZX BASIC?
You can read and process data from an array in JZX BASIC using a 'FOR' loop and array indexing. For example: 'FOR i=1 TO 10: PRINT a(i): NEXT i'.
What is the purpose of the 'RESTORE' statement in JZX BASIC?
The 'RESTORE' statement is used in JZX BASIC to reset the data pointer, allowing 'READ' statements to start reading data from the beginning again.

The ideal back-end app developer

What you’re looking to see on the JZX BASIC engineer at this point.

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

What does this simple code do in JZX BASIC?
10 PRINT "Hello, World!"
20 END
This code prints out the string 'Hello, World!' to the console. The 'END' statement signifies the end of the program.
What will be the output of this JZX BASIC code snippet?
10 LET A = 5
20 LET B = 10
30 PRINT A + B
40 END
This code will output '15'. It defines two variables, A and B, assigns them the values 5 and 10 respectively, and then prints the sum of A and B.
Can you explain what this JZX BASIC code does?
10 DIM A(5)
20 FOR I = 1 TO 5
30 LET A(I) = I * 2
40 NEXT I
50 FOR I = 1 TO 5
60 PRINT A(I)
70 NEXT I
80 END
This code declares an array 'A' with 5 elements, and then populates it with the numbers 2, 4, 6, 8, and 10. It then prints each element of the array.
What does this JZX BASIC code do?
10 LET A = 1
20 LET B = 0
30 IF A > B THEN GOTO 50
40 PRINT "B is greater"
50 PRINT "A is greater"
60 END
This code compares the values of variables A and B. If A is greater than B, it jumps to line 50 and prints 'A is greater'. If B is greater, it prints 'B is greater'. In this case, since A is greater than B, it will print 'A is greater'.

Wrap-up questions

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

How would you write a recursive function in JZX BASIC?
You can write a recursive function in JZX BASIC by having the function call itself within its own definition. This is typically done with a condition to prevent infinite recursion.
Describe the difference between local and global variables in JZX BASIC.
Local variables are declared within a subroutine or function and can only be accessed within that subroutine or function. Global variables, on the other hand, are declared outside any subroutine or function and can be accessed from anywhere in the program.
How would you implement error trapping in JZX BASIC?
You can implement error trapping in JZX BASIC using the 'ON ERROR GOTO' statement, which allows you to specify a line of code to be executed when an error occurs.
