SETL Programming Language(SETL Project - NYU Coura Developer Hiring Guide

The SETL Programming Language is a high-level programming language developed in the late 1960s at the New York University's Courant Institute of Mathematical Sciences. It was designed by Jack Schwartz and stands for "SET Language", referencing its basis in set theory, a branch of mathematical logic. SETL allows direct manipulation of sets as primitive values, providing powerful data manipulation abilities. The language had significant influence on the design of ABC and Python languages, showcasing its historical importance in computer science evolution. Its development and usage are extensively documented by NYU's SETL Project.

First 20 minutes

General SETL Programming Language(SETL Project - NYU Coura app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in SETL Programming Language(SETL Project - NYU Coura application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

What are the key features of SETL?
SETL is a high-level programming language based on the mathematical theory of sets. It supports advanced data structures like sets, tuples, and maps. It also provides powerful control structures and has a rich set of built-in functions.
How would you declare a set in SETL?
In SETL, a set is declared using the 'set' keyword followed by the set name and its elements enclosed in curly braces. For example, 'set mySet := {1, 2, 3};' declares a set named 'mySet' with elements 1, 2, and 3.
What is the purpose of the 'with' keyword in SETL?
The 'with' keyword in SETL is used to add an element to a set. For example, 'mySet with:= 4;' adds the element 4 to the set 'mySet'.
How would you remove an element from a set in SETL?
To remove an element from a set in SETL, you use the 'less' keyword. For example, 'mySet less:= 1;' removes the element 1 from the set 'mySet'.
What is the difference between a set and a tuple in SETL?
A set is an unordered collection of unique elements, while a tuple is an ordered collection of elements. Elements in a tuple can be repeated and the order of elements is significant.

Next 20 minutes

Specific SETL Programming Language(SETL Project - NYU Coura 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 declare a map in SETL?
In SETL, a map is declared using the 'map' keyword followed by the map name and its key-value pairs enclosed in square brackets. For example, 'map myMap := [1 |-> 'a', 2 |-> 'b'];' declares a map named 'myMap' with keys 1 and 2 mapped to values 'a' and 'b' respectively.
What is the purpose of the 'domain' function in SETL?
The 'domain' function in SETL returns the set of all keys in a map. For example, 'domain(myMap);' returns the set of keys in the map 'myMap'.
How would you iterate over a set in SETL?
To iterate over a set in SETL, you can use a 'for' loop. For example, 'for x in mySet do print(x); end;' prints all elements in the set 'mySet'.
What is the difference between the 'exists' and 'for all' quantifiers in SETL?
The 'exists' quantifier in SETL checks if there is at least one element in a set that satisfies a given condition, while the 'for all' quantifier checks if all elements in a set satisfy the condition.
How would you define a function in SETL?
In SETL, a function is defined using the 'procedure' keyword followed by the function name, parameters, and body. For example, 'procedure add(x, y); return x + y; end;' defines a function named 'add' that takes two parameters and returns their sum.

The ideal back-end app developer

What you’re looking to see on the SETL Programming Language(SETL Project - NYU Coura engineer at this point.

At this point, a skilled SETL Programming Language(SETL Project - NYU Coura engineer should demonstrate strong problem-solving abilities, proficiency in SETL Programming Language(SETL Project - NYU Coura 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 SETL Programming Language(SETL Project - NYU Coura.

What does the following SETL code do?
print([x ** 2 | x in {1..10}]);
This code prints the squares of all numbers from 1 to 10. It uses a list comprehension to generate a list of squares and then prints it.
What will be the output of the following SETL code?
x := {1, 2, 3, 4, 5};
print(#x);
The output will be '5'. The '#' operator in SETL returns the cardinality (size) of a set, so this code prints the size of the set x, which is 5.
What does the following SETL code do?
x := {1, 2, 3, 4, 5};
y := {4, 5, 6, 7, 8};
print(x + y);
This code prints the union of two sets x and y. The '+' operator in SETL performs set union, so it combines the elements of both sets without duplication.
What will be the output of the following SETL code?
procedure p;
begin
  x := 5;
  print(x);
end;

procedure q;
begin
  x := 10;
  print(x);
end;

p;
q;
The output will be '5' and '10'. The code defines two procedures p and q, each of which sets a local variable x to a different value and prints it. Then it calls both procedures.

Wrap-up questions

Final candidate for SETL Programming Language(SETL Project - NYU Coura 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 SETL Programming Language(SETL Project - NYU Coura application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What is the purpose of the 'om' value in SETL?
'om' in SETL stands for 'Omega' and represents an undefined value. It is used when a variable is declared but not yet assigned a value.
How would you handle exceptions in SETL?
SETL provides a 'catch' statement to handle exceptions. For example, 'catch E in print(E); end;' catches any exception 'E' and prints it.
What is the difference between the 'exit' and 'return' statements in SETL?
The 'exit' statement in SETL is used to terminate the execution of the current loop or procedure, while the 'return' statement is used to return a value from a function.
