Hiring guide for EGL (Enterprise Generation Language) Engineers

EGL (Enterprise Generation Language) Developer Hiring Guide

EGL (Enterprise Generation Language) is a high-level, modern programming language developed by IBM. It was created to simplify the development of complex business applications that often involve integration with other systems or services. EGL is platform-independent and can generate code in multiple languages such as Java, JavaScript, and COBOL. The main advantage of EGL is that it abstracts low-level technical details, allowing developers to focus on the business logic instead of struggling with system interfaces or communication protocols. This not only accelerates development but also reduces errors. EGL supports object-oriented concepts like encapsulation and inheritance but also includes capabilities for accessing relational databases easily. Its syntax resembles traditional programming languages like Pascal or PL/I which makes it easy for developers from different backgrounds to learn and adopt EGL. Another notable feature of this language is its built-in security features which ensure secure transactions when interacting with different systems in an enterprise environment. In conclusion, while being less known than mainstream languages such as Java or C#, Enterprise Generation Language offers powerful capabilities particularly suited for large-scale enterprise application development where integration between various systems plays a crucial role.

First 20 minutes

General EGL (Enterprise Generation Language) app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in EGL (Enterprise Generation Language) application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

What are the basic components of an EGL Program?
The basic components of an EGL Program are Program, Function, Record, Library, and Handler.
What is the purpose of using Handler in EGL?
Handlers in EGL are used for managing events and actions. They provide a mechanism to define what action should be taken when a specific event occurs.
Describe the difference between a Service and a Program in EGL.
A Service in EGL is a program that exposes functions that can be called from other programs, whereas a Program in EGL is a standalone program that can be run independently.
How do you define a variable in EGL?
In EGL, a variable is defined by specifying its name, followed by its type. For example, var1 int; defines a variable named var1 of type integer.
What are the different data types available in EGL?
EGL supports a variety of data types including int, smallint, string, boolean, date, time, timestamp, decimal, and more.

Next 20 minutes

Specific EGL (Enterprise Generation Language) 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 handle exceptions in EGL?
Exceptions in EGL are handled using the TRY, THROW, and CATCH statements. The TRY block contains the code that might throw an exception, the THROW statement is used to throw an exception, and the CATCH block contains the code to handle the exception.
What is the use of CALL statement in EGL?
The CALL statement in EGL is used to call a function or a service. It can also be used to call a program.
How would you implement inheritance in EGL?
Inheritance in EGL can be implemented using the EXTENDS keyword. The subclass specifies the superclass name after the EXTENDS keyword.
What is the purpose of using interfaces in EGL?
Interfaces in EGL are used to define a contract for classes. They specify what a class must do, but not how it does it. This allows for flexibility and loose coupling between classes.
Describe the difference between a record and a dictionary in EGL.
A record in EGL is a complex data type that contains a fixed number of fields of various data types, whereas a dictionary is a data structure that contains key-value pairs.

The ideal back-end app developer

What you’re looking to see on the EGL (Enterprise Generation Language) engineer at this point.

At this point, a skilled EGL (Enterprise Generation Language) engineer should demonstrate strong problem-solving abilities, proficiency in EGL (Enterprise Generation Language) 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 EGL (Enterprise Generation Language).

What does the following simple EGL code do?
HelloWorld function helloWorld() SysLib.writeStdout('Hello, world!'); end
This code defines a function called helloWorld that prints the string 'Hello, world!' to the standard output.
What does the following EGL code snippet do?
Type1 type1 = new Type1; type1.field1 = 'Test';
This code creates a new instance of Type1 and assigns the string 'Test' to its field1 property.
What does the following EGL code snippet do?
Array arr = new Array; arr[1] = 'One'; arr[2] = 'Two';
This code creates a new array, then assigns the string 'One' to the first index and the string 'Two' to the second index.
What does the following EGL code snippet do?
Thread thread = new Thread; thread.run(function() SysLib.writeStdout('Hello, world!'); end);
This code creates a new thread and runs a function that prints 'Hello, world!' to the standard output in that thread.

Wrap-up questions

Final candidate for EGL (Enterprise Generation Language) 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 EGL (Enterprise Generation Language) application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

How would you implement polymorphism in EGL?
Polymorphism in EGL can be implemented using interfaces and inheritance. A method defined in an interface can be implemented in multiple ways by different classes. Similarly, a method in a superclass can be overridden in a subclass.
What are the different types of records in EGL?
EGL supports several types of records including basic records, external type records, SQL records, and JSON records.
How would you access a database in EGL?
In EGL, databases can be accessed using SQL statements. These SQL statements are embedded in EGL code using the EXEC SQL statement.
