Zuse's Plankalkül, also known simply as Plankalkül, is recognized as the first high-level, non-von Neumann programming language. It was developed by German engineer Konrad Zuse between 1942 and 1945. However, it wasn't implemented or published until several decades later. The language was designed for engineering purposes, including the ability to handle logical operations and floating-point arithmetic. Its structure includes features such as conditional statements and loops. Despite its early development, Plankalkül had little influence on the design of subsequent programming languages due to its late publication and implementation.

First 20 minutes

General Zuse's Plankalkül app knowledge and experience

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

What is the historical significance of Zuse's Plankalkül?

Zuse's Plankalkül is historically significant as it is considered the first high-level, algorithmic programming language. It was developed by Konrad Zuse between 1943 and 1945.

What are the key features of Zuse's Plankalkül?

Key features of Zuse's Plankalkül include its ability to handle arrays, floating-point arithmetic, conditional statements, and loops. It also supports functions and subroutines.

How would you write a simple 'Hello, World!' program in Zuse's Plankalkül?

Zuse's Plankalkül was not designed for text processing or output, so it's not possible to write a 'Hello, World!' program in the traditional sense.

Describe the difference between Zuse's Plankalkül and modern programming languages.

While Zuse's Plankalkül introduced many concepts found in modern programming languages, it lacks many features we take for granted today, such as string manipulation, standard libraries, and a large user community.

What are the data types supported by Zuse's Plankalkül?

Zuse's Plankalkül supports boolean and floating-point data types.

Next 20 minutes

Specific Zuse's Plankalkül 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 implement a loop in Zuse's Plankalkül?

Zuse's Plankalkül supports loops through the use of conditional statements and jump instructions.

What is the syntax for defining a function in Zuse's Plankalkül?

In Zuse's Plankalkül, a function is defined using the 'P' keyword followed by the function name, parameters, and body.

How would you handle arrays in Zuse's Plankalkül?

Zuse's Plankalkül supports arrays and they can be defined using the 'V' keyword followed by the array name and size.

What are the control structures available in Zuse's Plankalkül?

Zuse's Plankalkül supports conditional statements and loops as control structures.

How would you implement conditional statements in Zuse's Plankalkül?

In Zuse's Plankalkül, conditional statements can be implemented using the 'IF' keyword followed by the condition and the code to execute if the condition is true.

At this point, a skilled Zuse's Plankalkül engineer should demonstrate strong problem-solving abilities, proficiency in Zuse's Plankalkül 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 Zuse's Plankalkül.

What does the following Plankalkül code do?
P1 max (V0[:8.0], V1[:8.0]) => R[:8.0] := V0[:8.0] ? V0[:8.0] >= V1[:8.0] -> V1[:8.0];
This code defines a function named 'max' which takes two arguments and returns the greater value between them.
What is the purpose of the '[:8.0]' in this Plankalkül code?
P1 max (V0[:8.0], V1[:8.0]) => R[:8.0] := V0[:8.0] ? V0[:8.0] >= V1[:8.0] -> V1[:8.0];
The '[:8.0]' is a type declaration in Plankalkül language. It specifies that the variable is an array of floating point numbers with up to 8 elements.
What does the following Plankalkül code do?
P1 sort (V0[:8.0]) => R[:8.0] := for i in 0..7 do for j in i+1..7 do V0[i] > V0[j] -> swap(V0[i], V0[j]); end; end;
This code implements the bubble sort algorithm. It sorts an array of floating point numbers in ascending order.
How does Plankalkül handle concurrency? Please explain using a code snippet.
P0 start => begin P1; P2; end
Plankalkül does not support explicit concurrency. However, the code above illustrates how programs can be structured to execute sequentially. The 'begin' and 'end' keywords enclose a block of code, ensuring that program P1 is executed before program P2.

Wrap-up questions

Final candidate for Zuse's Plankalkül 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 Zuse's Plankalkül application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What is the significance of the 'P' keyword in Zuse's Plankalkül?

In Zuse's Plankalkül, the 'P' keyword is used to define a function or procedure.

How would you handle floating-point arithmetic in Zuse's Plankalkül?

Zuse's Plankalkül supports floating-point arithmetic natively, so you can perform operations like addition, subtraction, multiplication, and division directly.

What are the limitations of Zuse's Plankalkül?

Limitations of Zuse's Plankalkül include its lack of support for string manipulation, limited data types, and the fact that it was never fully implemented during Zuse's lifetime.
