Ask the right questions to secure the right Harbour talent among an increasingly shrinking pool of talent.
Harbour is an open-source programming language, a cross-platform variant of the well-known Clipper language. It was first developed in 1999 by Antonio Linares to overcome limitations of the DOS-based Clipper and to provide a platform-independent solution. The name "Harbour" is inspired by its ability to port applications from one operating system to another with ease. Harbour's source code is hosted on GitHub, demonstrating its commitment to transparency and community involvement. Its robustness, efficiency, and compatibility make it a preferred choice for database-oriented applications.

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 Harbour, '==' is an exact equality operator. It checks if the values of two operands are equal or not. If the values are equal, then the condition becomes true.
In Harbour, error handling can be performed using the ErrorBlock() function. This function sets a new error block and returns the current one. When an error occurs, the error block is evaluated with the error object as an argument.
While both Harbour and xHarbour are compilers for the Clipper programming language, there are some differences. xHarbour extends the Clipper language with many new features and functions, while Harbour aims to be largely compatible with Clipper and focuses more on stability and speed.
Some key features of Harbour include portability across multiple operating systems, compatibility with Clipper language, support for multiple databases, and the ability to create GUI and console applications.
Harbour is a free, open-source compiler for the xBase superset language often referred to as Clipper. The goal of the Harbour project is to produce a cross-platform compiler that can be used in both desktop and web development.
A strong work ethic and reliability are important in meeting project deadlines and maintaining quality. The candidate should provide examples of their dedication and consistency in previous roles.
Experience with similar projects can indicate the candidate's ability to perform the job. They should be able to explain their role, the challenges they faced, and the outcomes of the projects.
The tech industry, including Harbour development, is constantly evolving. The candidate should show a willingness to learn new technologies and adapt to changes.
Most development projects require team collaboration. The candidate should show that they can communicate effectively, respect others' ideas, and contribute to a team-oriented environment.
Problem-solving skills are crucial in any development role. The candidate should be able to describe a situation where they used their problem-solving skills to overcome a challenge.
A strong understanding of Harbour programming language is essential for the role. The candidate should be able to explain complex concepts and demonstrate their knowledge through examples or past experiences.
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.
The HB_Inkey() function in Harbour is used to check whether a key has been pressed and to get the key code of the last key pressed.
In Harbour, '==' is an exact equality operator used for comparison, while ':=' is an assignment operator used to assign the value of right operand to the left operand.
Harbour natively does not support multithreading. However, it can be achieved by integrating with other languages such as C or C++, which do support multithreading.
The HB_OutStd() function in Harbour is used to output a string to the standard output device.
File handling in Harbour can be done using various built-in functions such as FOpen() to open a file, FRead() to read from a file, FWrite() to write to a file, and FClose() to close a file.
A skilled Harbour engineer should possess strong analytical skills, proficiency in using Harbour programming language, and excellent problem-solving abilities. Red flags would include lack of hands-on experience with related projects, poor communication skills, and inability to explain technical concepts clearly.

The final few interview questions for a Harbour candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.
To compile a Harbour program, you use the Harbour compiler with the filename as an argument. This produces an object file. Then, you use a C compiler to compile this object file into an executable. To run the program, you simply execute the resulting file.
Exception handling in Harbour can be done using the BEGIN SEQUENCE and RECOVER USING block. Any errors that occur within the BEGIN SEQUENCE block are caught and passed to the RECOVER USING block.
In Harbour, HB_DtoC() is used to convert a date value to a string, while HB_CtoD() is used to convert a string to a date value.
The HB_PCount() function in Harbour is used to get the count of parameters that have been passed to a procedure or function.
The HB_ValToExp() function in Harbour is used to convert a value to a string expression. It can be useful for debugging purposes.
