Hiring guide for WATFIV and WATBOL (Waterloo Fortran and Waterloo B Engineers

WATFIV and WATBOL (Waterloo Fortran and Waterloo B Developer Hiring Guide

WATFIV and WATBOL are programming languages developed at the University of Waterloo, Canada. WATFIV, or Waterloo Fortran IV, is an extension of the FORTRAN IV programming language. It was developed in the late 1960s and was one of the first student-oriented programming languages. WATFIV was designed to be easy to learn and use, making it ideal for beginners. It was also one of the first languages to provide interactive debugging features. WATFIV was widely adopted in educational institutions for teaching computer programming and numerical methods. WATBOL, or Waterloo Basic Object-oriented Language, is a version of the BASIC programming language. It was developed in the 1970s and was designed to be a simple, easy-to-learn language for beginners. WATBOL includes features for structured programming and data abstraction, which were innovative at the time. It also includes a powerful string manipulation capability, making it suitable for text processing tasks. Both WATFIV and WATBOL were designed with the goal of making programming more accessible and understandable for students and beginners. They were used extensively in computer science education and have influenced the design of many subsequent programming languages.

First 20 minutes

General WATFIV and WATBOL (Waterloo Fortran and Waterloo B app knowledge and experience

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

What are the main features of WATFIV and WATBOL?
WATFIV and WATBOL are high-level programming languages developed at the University of Waterloo. They are extensions of the FORTRAN IV and BASIC languages respectively, designed to be easy to learn and use. They have features such as structured programming constructs, interactive debugging facilities, and extensive error checking.
How would you debug a program in WATFIV and WATBOL?
WATFIV and WATBOL provide interactive debugging facilities. You can set breakpoints, watch variables, and step through the code. You can also use the PRINT statement to display the values of variables at certain points in the program.
What are the uses of the DATA statement in WATFIV?
The DATA statement in WATFIV is used to initialize variables or arrays at the time of their declaration. It allows to specify initial values for one or more variables in the program.
How would you handle arrays in WATBOL?
In WATBOL, arrays are handled using the DIM statement. The statement DIM A(10) would declare an array A with 10 elements. You can then access or modify the elements of the array using their indices.
Describe the difference between the IF and the SELECT CASE statements in WATFIV.
The IF statement in WATFIV is used to test a condition and execute a block of code if the condition is true. The SELECT CASE statement is used when you need to test a variable against a list of values or ranges of values. It is more efficient and readable than a series of IF statements when there are many conditions to test.

Next 20 minutes

Specific WATFIV and WATBOL (Waterloo Fortran and Waterloo B 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.

What are the control structures available in WATBOL?
WATBOL provides a variety of control structures for structured programming, including IF-THEN-ELSE for conditional execution, FOR-NEXT and WHILE-WEND for loops, and SELECT CASE for multi-way selection.
How would you handle errors in WATFIV and WATBOL?
WATFIV and WATBOL provide extensive error checking facilities. When an error occurs, the system displays an error message with the line number and a description of the error. You can also use the ON ERROR statement to specify an error handling routine that will be executed when an error occurs.
Describe the difference between the GOTO and the DO WHILE statements in WATFIV.
The GOTO statement in WATFIV is used to transfer control unconditionally to another part of the program. The DO WHILE statement is a loop construct that repeats a block of code while a condition is true. The use of GOTO is generally discouraged in modern programming as it can make the code difficult to understand and maintain.
What are the string manipulation functions available in WATBOL?
WATBOL provides a variety of string manipulation functions, including LEN to get the length of a string, SUBSTR to extract a substring, CONCAT to concatenate two strings, and TRIM to remove leading and trailing spaces.
How would you define and use functions in WATFIV?
In WATFIV, functions are defined using the FUNCTION statement, followed by the function name and a list of parameters. The function body consists of a block of code that performs a specific task and returns a value. Functions can be called in expressions in the same way as built-in functions.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with WATFIV and WATBOL (Waterloo Fortran and Waterloo B.

What does this simple WATFIV code do?
PROGRAM SIMPLE
READ(5,10) A,B
10 FORMAT(2F5.1)
WRITE(6,20) A,B
20 FORMAT(' A = ',F5.1,' B = ',F5.1)
END
This code reads two floating point numbers from the input, assigns them to variables A and B, and then prints them out with the labels 'A =' and 'B ='.
What will be the output of this WATBOL code?
100 LET A$ = 'HELLO'
110 PRINT A$; ' WORLD'
120 END
The output of this code will be 'HELLO WORLD'.
What does this WATFIV code do with arrays?
PROGRAM ARRAYS
DIMENSION A(10)
DO 10 I=1,10
A(I) = I
10 CONTINUE
WRITE(6,20) (A(I),I=1,10)
20 FORMAT(10I5)
END
This code initializes an array of 10 integers, assigns each element the value of its index, and then prints out all the elements of the array.
What does this WATBOL code do with threading?
100 LET A = 1
110 FOR I = 1 TO 10
120 LET A = A + 1
130 NEXT I
140 PRINT A
150 END
WATBOL does not support threading or concurrency. This code simply increments a variable A 10 times in a loop and then prints out the result, which will be 11.

Wrap-up questions

Final candidate for WATFIV and WATBOL (Waterloo Fortran and Waterloo B 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 WATFIV and WATBOL (Waterloo Fortran and Waterloo B application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between local and global variables in WATFIV and WATBOL.
In WATFIV and WATBOL, a local variable is one that is declared within a procedure or function and is only visible within that procedure or function. A global variable is one that is declared outside all procedures and functions and is visible throughout the program.
What are the file handling capabilities of WATFIV and WATBOL?
WATFIV and WATBOL provide facilities for handling files. You can open a file for input or output using the OPEN statement, read or write data using the READ or WRITE statement, and close the file using the CLOSE statement. You can also test for end-of-file using the EOF function.
How would you handle exceptions in WATFIV and WATBOL?
In WATFIV and WATBOL, exceptions are handled using the ON ERROR statement, which specifies an error handling routine that will be executed when an error occurs. The error handling routine can use the ERR function to get the error code and the ERL function to get the line number where the error occurred.
