First 20 minutes

General Alice ML v20.0 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Alice ML v20.0 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you install Alice ML v20.0 on a Linux system?
You would download the source code from the official website, then use the terminal to navigate to the directory where the source code is located. From there, you would run the './configure' command, followed by 'make' and 'make install'.
What are the main features of Alice ML v20.0?
Alice ML v20.0 includes features such as a rich set of data types, first-class functions, pattern matching, and concurrent and distributed programming support.
Describe the difference between Alice ML and other ML languages like OCaml or Haskell.
Alice ML includes a rich set of features for concurrent, distributed, and constraint programming that are not present in OCaml or Haskell. It also has a more advanced type system with support for higher-order modules and first-class components.
How would you handle errors in Alice ML v20.0?
Alice ML v20.0 uses a system of exceptions for error handling. You can define your own exceptions, raise them using the 'raise' keyword, and handle them using the 'handle' keyword in conjunction with pattern matching.
What are the advantages of using Alice ML v20.0 for concurrent programming?
Alice ML v20.0 has built-in support for concurrent programming, including lightweight threads, asynchronous message passing, and futures. This makes it easier to write concurrent programs compared to languages without these features.

Next 20 minutes

Specific Alice ML v20.0 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 synchronous and asynchronous message passing in Alice ML v20.0.
In synchronous message passing, the sender blocks until the receiver is ready to receive the message. In asynchronous message passing, the sender does not block and the message is stored until the receiver is ready.
How would you implement a distributed system in Alice ML v20.0?
You would use Alice ML's built-in support for distributed programming. This includes the ability to create remote references to objects, send messages to these objects, and handle messages from these objects.
What are the main uses of futures in Alice ML v20.0?
Futures in Alice ML v20.0 are used for concurrent programming. They represent a value that may not yet be available, and they allow the program to continue executing while waiting for the value.
Describe the difference between a future and a promise in Alice ML v20.0.
A future is a value that may not yet be available, while a promise is a placeholder for a value that will be provided in the future. When a promise is fulfilled, any futures associated with it are automatically updated with the provided value.
How would you use pattern matching in Alice ML v20.0?
Pattern matching in Alice ML v20.0 is used with the 'case' keyword. You can match on values, types, and structures, and you can use variables and wildcards in your patterns.

The ideal back-end app developer

What you’re looking to see on the Alice ML v20.0 engineer at this point.

At this point, a skilled Alice ML v20.0 engineer should demonstrate strong problem-solving abilities, proficiency in Alice ML v20.0 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 Alice ML v20.0.

What does the following Alice ML code do?
val x = 10;
val y = 20;
val z = x + y;
This code declares two integer variables x and y, assigns them the values 10 and 20 respectively, and then adds these two values together and assigns the result to a new variable z.
What will be the output of the following Alice ML code?
val x = "Hello";
val y = "World";
val z = x ^ " " ^ y;
print z;
This code concatenates the strings 'Hello' and 'World' with a space in between and assigns the result to a new variable z. It then prints the value of z, which will be 'Hello World'.
What does the following Alice ML code do?
val arr = #[1, 2, 3, 4, 5];
val sum = Array.foldl (op +) 0 arr;
This code declares an array arr with five elements. It then uses the Array.foldl function to sum up the elements of the array, starting with an initial value of 0.
What does the following Alice ML code do?
val t = Thread.fork (fn () => (Thread.delay (Time.seconds 1); print "Hello"));
This code creates a new thread that waits for one second and then prints the string 'Hello'.

Wrap-up questions

Final candidate for Alice ML v20.0 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 Alice ML v20.0 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the benefits of Alice ML v20.0's support for higher-order modules?
Higher-order modules in Alice ML v20.0 allow you to abstract over modules, just like you can abstract over values with functions. This leads to more modular and reusable code.
Describe the difference between a function and a procedure in Alice ML v20.0.
In Alice ML v20.0, a function is a piece of code that takes input, performs computations, and returns a value. A procedure, on the other hand, is a piece of code that performs actions but does not return a value.
How would you implement a constraint solver in Alice ML v20.0?
You would use Alice ML v20.0's built-in support for constraint programming. This includes the ability to define variables, constraints, and domains, and to use the 'solve' function to find solutions.
