Hiring guide for TIE Engineers

TIE Developer Hiring Guide

**TIE (programming language)** * TIE was developed in the 1960s at the Massachusetts Institute of Technology (MIT). * It was designed as a general-purpose language for scientific computing. * TIE is a compiled language, meaning that it is translated into machine code before it is executed. * TIE is still in use today, although it is not as popular as some other programming languages. * For more information, see [the TIE website](https://tie.org/).

First 20 minutes

General TIE app knowledge and experience

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

How would you explain the role of a TIE developer?
A TIE developer is responsible for designing, developing, and implementing applications that are aligned with business and IT strategies and comply with the organization's architectural standards. They also involve in the full systems life cycle and is responsible for designing, coding, testing, implementing, maintaining and supporting applications software.
What are the key skills required for a TIE developer?
A TIE developer should have strong analytical and problem-solving skills, detailed knowledge of programming languages like Java, C++, SQL, etc., understanding of software development methodologies, good testing and debugging skills, knowledge of data structures and algorithms, and good communication skills.
Describe the difference between a TIE developer and a software developer.
While both TIE developers and software developers work on designing and creating software applications, the key difference lies in their areas of focus. A TIE developer primarily focuses on developing applications that are aligned with business and IT strategies and comply with the organization's architectural standards. On the other hand, a software developer is more general and can work on any part of the development process, from initial planning to final testing and deployment.
How would you handle a situation where you are given a tight deadline for a project?
I would first break down the project into smaller tasks and prioritize them based on their importance and urgency. I would then create a detailed schedule and stick to it. If necessary, I would discuss with my manager about the possibility of extending the deadline or getting additional resources.
What are some common challenges faced by a TIE developer and how would you overcome them?
Some common challenges include dealing with complex business requirements, managing tight deadlines, and keeping up with the latest technologies. To overcome these challenges, I would constantly improve my technical skills, use effective project management techniques, and stay updated with the latest industry trends.

Next 20 minutes

Specific TIE 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 a situation where your code is not working as expected?
I would first try to understand the problem by debugging the code. If the problem persists, I would seek help from my colleagues or use online resources. I would also write tests to ensure that the code is working as expected.
Describe the difference between procedural and object-oriented programming.
Procedural programming is a programming paradigm that uses a linear or top-down approach and treats data and procedures as two separate entities. On the other hand, object-oriented programming is a programming paradigm that uses a bottom-up approach and combines data and procedures into a single entity called an object.
What are some best practices for coding that you follow?
Some best practices that I follow include writing clean and readable code, using meaningful variable and function names, commenting the code, following the DRY (Don't Repeat Yourself) principle, and testing the code regularly.
How would you ensure the quality of your code?
I would ensure the quality of my code by writing tests, using code reviews, following coding standards and best practices, and using tools for static code analysis.
What are some security measures that you would take while developing an application?
Some security measures include validating and sanitizing user input, using secure communication protocols, encrypting sensitive data, using secure coding practices, and regularly updating and patching the software.

The ideal back-end app developer

What you’re looking to see on the TIE engineer at this point.

At this point, a skilled TIE engineer should demonstrate strong problem-solving abilities, proficiency in TIE 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 TIE.

What does the following JavaScript code do?
const a = [1, 2, 3];
const b = [...a, 4, 5];
This code creates a new array 'b' that contains all elements of array 'a' followed by elements 4 and 5. It's using the spread operator to copy elements from one array to another.
What will be the output of the following JavaScript code?
`const str = 'Hello';
The output will be 'HelloHelloHello'. The repeat() method constructs and returns a new string which contains the specified number of copies of the string on which it was called, concatenated together.
What does the following JavaScript code do?
const arr = [1, 2, 3, 4, 5];
const sum = arr.reduce((a, b) => a + b, 0);
This code calculates the sum of all elements in the array 'arr'. The reduce() function applies a function against an accumulator and each element in the array (from left to right) to reduce it to a single output value.
What does the following JavaScript code do?
const promise1 = new Promise((resolve, reject) => {
  setTimeout(resolve, 500, 'one');
const promise2 = new Promise((resolve, reject) => {
  setTimeout(resolve, 100, 'two');
Promise.race([promise1, promise2]).then((value) => {
The code creates two promises that resolve after different intervals. It then uses Promise.race() to log the value of the promise that resolves or rejects first. In this case, 'two' will be logged because promise2 resolves first.

Wrap-up questions

Final candidate for TIE 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 TIE application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between a relational database and a NoSQL database.
A relational database uses a structured schema and SQL for querying, and is best suited for complex queries and transactions. A NoSQL database does not use a structured schema, supports a variety of data models, and is best suited for handling large volumes of data and for scalability.
How would you handle a situation where a project is not going as planned?
I would first identify the issues causing the delay and come up with a plan to address them. I would then communicate the situation to the stakeholders and ask for their suggestions. If necessary, I would revise the project plan and adjust the timeline.
What are some performance optimization techniques that you would use?
Some performance optimization techniques include using efficient algorithms and data structures, optimizing database queries, using caching, minimizing the use of resources, and using load balancing.
