Ask the right questions to secure the right GAP talent among an increasingly shrinking pool of talent.
GAP is a computer software programing language used in mathematics. It was developed in the early 1980s at the University of Cambridge by Robin Chapman and John Cannon. GAP is free and open-source software, and it is available for Windows, Mac, and Linux. It is used by mathematicians around the world to study a wide variety of problems in algebra, geometry, and number theory.
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 GAP, you can define a function using the 'function' keyword, followed by a list of parameters in parentheses, and then the function body enclosed in 'end'.
The 'Size' function in GAP is used to determine the size of a group, list, or other collection of elements.
You can create a list in GAP using square brackets. For example, '[1, 2, 3]' creates a list of integers.
The basic data types in GAP include integers, rationals, cyclotomics, booleans, lists, records, and functions.
You can install GAP on a Linux system by downloading the source code from the official GAP website, extracting the archive, and then compiling the source code using the 'configure' and 'make' commands.
Knowledge of algorithms and data structures is essential for efficient coding and optimization in GAP development.
Past experience and projects can provide concrete evidence of the candidate's ability and expertise in GAP development.
The field of software development is constantly evolving, so it's important for a developer to be adaptable and eager to learn new technologies.
Good communication skills are necessary for understanding project requirements and collaborating with team members.
A strong grasp of GAP language is fundamental to perform well in the role.
This is crucial as a GAP developer often needs to solve complex coding issues and develop innovative solutions.
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.
You can use the 'Solution' function in GAP to solve a system of linear equations. The function takes two arguments: a matrix representing the coefficients of the equations, and a list representing the right-hand side of the equations.
The 'IsElement' function in GAP is used to determine whether a given object is an element of a specified collection, such as a group or a list.
You can compute the order of a permutation group in GAP using the 'Size' function. For example, 'Size(Group((1,2,3), (4,5)))' would return the order of the permutation group generated by the permutations (1,2,3) and (4,5).
In GAP, a list is an ordered collection of elements, while a set is an unordered collection of unique elements. Lists can contain duplicate elements and their order matters, while in sets, order does not matter and duplicates are not allowed.
Key features of GAP include its ability to perform computations in algebraic structures, its extensive library of algebraic algorithms, and its support for programming and scripting.
At this point, a skilled GAP engineer should demonstrate strong technical knowledge, problem-solving abilities, and excellent communication skills. Red flags include a lack of detail in responses, inability to articulate complex concepts, or an absence of practical experience with GAP engineering tools and methodologies.

You can use the 'AutomorphismGroup' function in GAP to compute the automorphism group of a given group. The function takes one argument, the group, and it returns the group of all automorphisms of the given group.
'StructureDescription' returns a string describing the structure of a finite group in terms of known simple groups, while 'IdGroup' returns a pair of integers that uniquely identify a given finite group up to isomorphism.
To write and run a GAP script, you first create a text file with the '.g' extension, write your GAP code in this file, and then run the script using the 'gap' command followed by the name of the script file.
You can use the 'Centralizer' function in GAP to compute the centralizer of an element in a group. The function takes two arguments: the group and the element, and it returns the set of all elements in the group that commute with the given element.
'IsSubset' checks if a collection of elements is a subset of another collection, while 'IsSubgroup' checks if a group is a subgroup of another group. The difference lies in the structure being considered: 'IsSubset' works with any collections, while 'IsSubgroup' specifically works with group structures.
