Ask the right questions to secure the right ISWIM talent among an increasingly shrinking pool of talent.
ISWIM (Initial System for Interactive Mathematical Applications) is a computer programming language designed in 1967 by Christopher Strachey. It was one of the first interactive programming languages, and was used to develop a number of early computer algebra systems.

The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
ISWIM has several advantages over other programming languages. Its simple syntax and strong type system make it easy to learn and use, and its support for functional programming allows for concise and readable code. Additionally, its garbage collector automatically frees up memory that is no longer in use, which can help improve performance.
ISWIM has a strong type system that helps prevent many common errors. However, if an error does occur, it's important to understand the error message and use it to debug the code. Additionally, it's a good practice to write tests for your code to ensure it behaves as expected.
ISWIM differs from other programming languages in several ways. Firstly, it's a high-level language, which means it's more abstract and easier to read and write than low-level languages. Secondly, it has a strong type system, which helps prevent errors. Lastly, it supports functional programming, which is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data.
ISWIM has several key features, including a simple syntax, a strong type system, and a high level of abstraction. It also supports functional programming, which allows for more concise and readable code. Additionally, ISWIM has a garbage collector, which automatically frees up memory that is no longer in use.
ISWIM, or 'If you See What I Mean', is a computer programming language that was designed to be easy to learn and use. It's a high-level language that uses a simple syntax and a strong type system to help prevent errors. It's also designed to be easy to compile and execute, making it a good choice for beginners and experienced programmers alike.
Understanding the lifecycle is important for planning, designing, building, testing, and maintaining software effectively.
This is important as it shows that the candidate can manage their time effectively and deliver work on schedule.
Good communication is essential in a development team to ensure everyone is on the same page and to avoid misunderstandings.
This is important because effective use of data structures and algorithms can greatly improve the performance of the software.
Problem-solving skills are key in software development, as they will often need to troubleshoot and resolve issues that arise in coding.
This is crucial as it is the primary language they will be using in their role as an ISWIM developer.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
In ISWIM, strong typing means that the type of a variable is checked at compile time, and any type errors are caught before the program is run. This can help prevent many common errors. On the other hand, weak typing would mean that type checking is done at runtime, and it's possible for a variable to hold values of different types at different times.
Implementing a complex algorithm in ISWIM involves breaking down the problem into smaller, manageable parts, and then writing functions to solve each part. It's important to write clear, readable code and to use the strong type system to prevent errors. Additionally, it's a good practice to write tests for your code to ensure it behaves as expected.
While ISWIM has many advantages, it also has some limitations. For example, it's not as widely used as some other languages, so there may be fewer resources and tools available. Additionally, because it's a high-level language, it may not be as efficient as low-level languages for certain tasks.
Functional programming in ISWIM treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. On the other hand, procedural programming is a programming paradigm based on the concept of the procedure call. Procedures, also known as routines, subroutines, or functions, simply contain a series of computational steps to be carried out.
Optimizing code in ISWIM involves several steps. Firstly, it's important to understand the code and identify any potential bottlenecks. Then, you can use various techniques to optimize the code, such as reducing the number of function calls, using more efficient data structures, or parallelizing the code if possible.
A skilled ISWIM engineer should demonstrate deep technical knowledge, problem-solving skills, and strong communication abilities. Red flags include inability to explain complex concepts simply, lack of practical experience or application of knowledge, and poor interpersonal skills.

The final few interview questions for a ISWIM candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.
Building a large-scale application in ISWIM involves designing a robust architecture, writing clear and efficient code, and thoroughly testing the application to ensure it behaves as expected. It's also important to consider performance and scalability, and to use tools and practices such as version control and continuous integration to manage the development process.
Some challenges of working with ISWIM include its relative obscurity, which means there may be fewer resources and tools available, and its strong typing, which can be restrictive. To overcome these challenges, it's important to seek out resources and communities that can provide support, and to use the strong typing to your advantage by preventing errors.
Garbage collection in ISWIM automatically frees up memory that is no longer in use, which can help improve performance and prevent memory leaks. On the other hand, manual memory management requires the programmer to explicitly free up memory when it's no longer needed, which can be more complex and error-prone.
Debugging a complex piece of code in ISWIM involves understanding the code, identifying the problem, and then using various techniques to solve it. This could include using a debugger, adding print statements to the code, or writing tests to isolate the problem.
Testing code in ISWIM involves writing tests for each function to ensure it behaves as expected. It's important to test both normal and edge cases. Additionally, it's a good practice to use a test framework, which can automate the testing process and provide useful feedback.
