Hiring guide for Genie Engineers

Genie Developer Hiring Guide

The Genie programming language is a modern, statically typed language that was developed as part of the GNOME project. It was designed in 2008 by Jamie McCracken to offer a simpler syntax than its predecessor, Vala. Genie uses an indentation-based syntax similar to Python, making it easier to read and write for developers. The language is primarily used for developing applications on the GNOME desktop environment. Source code written in Genie can be compiled into C code, providing high performance and wide platform support.

First 20 minutes

General Genie app knowledge and experience

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

How would you define Genie Framework?
Genie Framework is a high-level machine learning library built on top of PyTorch. It provides a unified and flexible interface for a variety of tasks such as classification, regression, and ranking.
What are the main components of Genie Framework?
The main components of Genie Framework are the model, the loss function, the data loader, and the optimizer.
Describe the difference between Genie and other machine learning libraries.
Genie is designed to be more flexible and easier to use than other libraries. It provides a unified interface for a variety of tasks, and it is built on top of PyTorch, which allows for dynamic computation graphs and efficient GPU computation.
How would you handle overfitting in a Genie model?
Overfitting can be handled in a Genie model by using techniques such as regularization, dropout, and early stopping. Additionally, using a validation set to monitor the model's performance can help detect overfitting.
What are the steps to train a model in Genie?
The steps to train a model in Genie are: define the model, define the loss function, define the data loader, define the optimizer, and then use a loop to iterate over the data and update the model's weights.

Next 20 minutes

Specific Genie 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 implement a custom loss function in Genie?
To implement a custom loss function in Genie, you would need to define a new class that inherits from the Loss class and implement the forward method.
What are the benefits of using Genie for machine learning tasks?
The benefits of using Genie for machine learning tasks include its flexibility, ease of use, and the fact that it is built on top of PyTorch, which allows for dynamic computation graphs and efficient GPU computation.
Describe the difference between a Genie model and a PyTorch model.
A Genie model is a high-level abstraction over a PyTorch model. It provides a unified interface for a variety of tasks, while a PyTorch model is a lower-level construct that requires more manual configuration.
How would you handle missing data in a Genie model?
Missing data in a Genie model can be handled by using techniques such as imputation, where missing values are filled in based on the values of other data points.
What are the steps to deploy a Genie model?
The steps to deploy a Genie model are: train the model, save the model's weights, write a script to load the weights and make predictions, and then deploy that script on a server or in the cloud.

The ideal back-end app developer

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

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

What does the following Genie code do?
init
    print "Hello, World!"
This code prints the string 'Hello, World!' to the console.
What is the output of the following Genie code?
var a = 5
var b = 10
print a + b
The output of this code will be 15. It adds the values of variables 'a' and 'b' and prints the result.
What does the following Genie code do?
var list = [1, 2, 3, 4, 5]
for i in list
    print i
This code prints each element in the 'list' array to the console. It iterates over the array using a for loop.
What does the following Genie code do?
class ThreadExample
    def run()
        print "Thread is running"
var t = new ThreadExample()
t.run()
This code creates a new instance of the 'ThreadExample' class and calls its 'run' method, which prints 'Thread is running' to the console.

Wrap-up questions

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

How would you optimize the performance of a Genie model?
The performance of a Genie model can be optimized by using techniques such as hyperparameter tuning, feature selection, and using more complex models.
Describe the difference between batch and online learning in Genie.
Batch learning in Genie involves training the model on the entire dataset at once, while online learning involves updating the model incrementally with each new data point.
How would you handle imbalanced data in a Genie model?
Imbalanced data in a Genie model can be handled by using techniques such as oversampling the minority class, undersampling the majority class, or using a cost-sensitive loss function.
