ALGOL 68 Genie+ is a modern, open-source interpreter for the ALGOL 68 programming language. Developed by Marcel van der Veer, it was designed to be an accurate representation of the Revised Report on ALGOL 68. The software provides a comprehensive learning environment for this historically significant language, which influenced many subsequent programming languages including C and Pascal. It supports both Windows and Unix-based systems with its robust features and user-friendly interface. This software serves as an important tool in understanding the evolution of computer programming languages (Source: algol68.org).

First 20 minutes

General ALGOL 68 Genie+ app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in ALGOL 68 Genie+ 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 ALGOL 68 Genie+?

You can declare a variable in ALGOL 68 Genie+ using the syntax 'INT variable_name := value'. For example, 'INT a := 10'.

What are the basic data types in ALGOL 68 Genie+?

The basic data types in ALGOL 68 Genie+ are INT (integer), REAL (floating point), BOOL (boolean), CHAR (character), and STRING (string).

Describe the difference between 'IF' and 'CASE' statements in ALGOL 68 Genie+.

'IF' is used when you want to test a condition and execute a block of code if the condition is true. 'CASE' is used when you want to test a variable against a list of values and execute the block of code corresponding to the matching value.

How would you define a function in ALGOL 68 Genie+?

You can define a function in ALGOL 68 Genie+ using the 'PROC' keyword. For example, 'PROC function_name = (INT a, INT b)INT: a + b;'.

What are the control structures available in ALGOL 68 Genie+?

The control structures available in ALGOL 68 Genie+ are 'IF', 'CASE', 'WHILE', 'UNTIL', 'FOR', and 'DO'.

Next 20 minutes

Specific ALGOL 68 Genie+ 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 'WHILE' and 'UNTIL' loops in ALGOL 68 Genie+.

'WHILE' loop continues execution as long as the condition is true. 'UNTIL' loop continues execution as long as the condition is false.

How would you handle exceptions in ALGOL 68 Genie+?

You can handle exceptions in ALGOL 68 Genie+ using the 'ON' keyword. For example, 'ON (exception_name) : (exception_handler);'.

What are the different modes of parameters in ALGOL 68 Genie+?

The different modes of parameters in ALGOL 68 Genie+ are 'IN' (input), 'OUT' (output), and 'INOUT' (input/output).

Describe the difference between 'IN' and 'OUT' parameters in ALGOL 68 Genie+.

'IN' parameters are used to pass values to a function, and 'OUT' parameters are used to get values from a function.

How would you create an array in ALGOL 68 Genie+?

You can create an array in ALGOL 68 Genie+ using the '[]' syntax. For example, 'INT array_name[5] := (1, 2, 3, 4, 5);'.

Oops! Something went wrong while submitting the form.

At this point, a skilled ALGOL 68 Genie+ engineer should demonstrate strong problem-solving abilities, proficiency in ALGOL 68 Genie+ 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 ALGOL 68 Genie+.

What does this simple ALGOL 68 Genie+ code do?
BEGIN
  INT a := 5;
  INT b := 10;
  INT c := a + b;
  print((c, new line))
END
This code declares two integer variables 'a' and 'b', assigns them the values 5 and 10 respectively, then adds them together and assigns the result to a third variable 'c'. It then prints the value of 'c', which will be 15.
What will be the output of this ALGOL 68 Genie+ code?
BEGIN
  REAL x := 3.14;
  REAL y := 2.71;
  REAL z := x * y;
  print((z, new line))
END
This code multiplies two real numbers 3.14 and 2.71 and assigns the result to a variable 'z'. It then prints the value of 'z', which will be approximately 8.5094.
What does this ALGOL 68 Genie+ code do?
BEGIN
  [1:5]INT arr := (1, 2, 3, 4, 5);
  FOR i FROM LWB arr TO UPB arr DO
    arr[i] := arr[i] * 2;
  OD
  print((arr, new line))
END
This code declares an array of integers 'arr' with 5 elements. It then loops over the array and multiplies each element by 2. The modified array is then printed, which will be (2, 4, 6, 8, 10).
What does this ALGOL 68 Genie+ code do?
BEGIN
  SEMA s := INIT SEMA(1);
  PROC p = VOID: (
    DOWN(s);
    print(('Hello, world!', new line));
    UP(s)
  );
  PAR BEGIN
    p;
    p
  END
END
This code declares a semaphore 's' and a procedure 'p'. The procedure 'p' prints 'Hello, world!' but only after acquiring the semaphore 's'. The code then runs two instances of 'p' in parallel. Due to the semaphore, the two print statements will not overlap.

Wrap-up questions

Final candidate for ALGOL 68 Genie+ 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 ALGOL 68 Genie+ application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of operators in ALGOL 68 Genie+?

The different types of operators in ALGOL 68 Genie+ are arithmetic operators, relational operators, logical operators, and bitwise operators.

Describe the difference between 'AND' and 'OR' operators in ALGOL 68 Genie+.

'AND' operator returns true if both operands are true, and 'OR' operator returns true if either of the operands is true.

How would you perform file I/O operations in ALGOL 68 Genie+?

You can perform file I/O operations in ALGOL 68 Genie+ using the 'open', 'read', 'write', and 'close' procedures.
