10 common TensorFlow interview questions

Review these 10 questions before your next TensorFlow interview to help you prepare strong responses.

1. What are the key components of TensorFlow?

What they’re really asking: Do you know how to use TensorFlow fundamentals?

TensorFlow has different components that work together, starting with the tensor as the core framework for TensorFlow. You can create a tensor with input data or calculations to form a multidimensional data array.

Other key components include:

• Graphs: Graphs collect and describe series computations.

• Variables: Variables are tensors that can change values when you run operations.

• Nodes: Nodes represent mathematical operations like addition or multiplication.

2. How do you build a neural network in TensorFlow?

What they’re really asking: Do you understand the relationship between neural networks and TensorFlow use?

Creating neural networks in TensorFlow is a multistep process, and employers want to know more about your knowledge of the different skills used in building these networks. You will want to cover skills such as preparing data sets, verifying and visualizing data, adding layers, and building neural networks on top of layers.

3. What is TensorFlow's data pipeline?

What they’re really asking: Can you explain your TensorFlow data input skills?

TensorFlow relies on data using the tf.data API to build complex input data pipelines from reusable sources. It’s important to cover not only tf.data but also data source constructs and data transformation constructs.

4. What is TensorFlow's Keras API?

What they’re really asking: Can you solve machine-learning problems in TensorFlow?

Keras is a high-level API on the TensorFlow platform that provides an interface for machine-learning problems using deep learning. It can be helpful to mention your understanding of the different steps Keras covers in a machine-learning workflow concerning data processing, hyperparameter tuning, and deployment.

5. How do you handle overfitting and underfitting in TensorFlow?

What they’re really asking: Do you understand how to balance data?

With TensorFlow, you can have issues with both too much training data and not enough training data, which show up with overfitting and underfitting TensorFlow training data. Employers want to know if you have the skills to recognize these issues and find the right balance or address them when optimizing data to focus on the most prominent patterns.

6. What are the different types of optimizers in TensorFlow?

What they’re really asking: Do you know how to deploy different optimizers?

Optimizers are algorithms you can use in TensorFlow concerning a model’s trainable parameters to minimize a loss function. Essential optimizers to familiarize yourself with include:

• Gradient descent: Use this optimizer class to update a list of variables based on a gradient list. For example, you can use a basic gradient descent optimizer by subtracting its gradient based on a learned rate.

• Adaptive moment estimation (Adam): The Adam optimizer handles momentum and root mean square propagation (RMSP).

7. How do you deploy TensorFlow models?

What they’re really asking: Can you follow the TensorFlow deployment process?

Deploying a TensorFlow model is a technical multistep process, and employers will want to know if you can follow the necessary steps to complete a model for deployment. Consider mastering these steps before an interview, focusing on how to create and build projects before deploying them.

8. What is LiteRT?

What they’re really asking: Are you comfortable using TensorLite on a local platform?

LiteRT is a good TensorFlow option if you want to run on your devices. It can work on platforms such as Android and iOS, which adds flexibility when dealing with specific models or a specialized implementation.

Note: LiteRT was previously called TensorFlow Lite. Referring to it as its current name helps show you are on top of changes in technology.

9. What computer languages are you proficient in?

What they’re really asking: Do you have the foundational skills for TensorFlow?

It’s vital to know the different characteristics of TensorFlow, but it helps to pair these specialized skills with foundational skills such as Python and C++. It’s also good to mention projects in which you’ve used other foundational skills with success, such as complete forms of data and TensorFlow’s relationship with AI technologies.

10. What questions do you have for me?

What they’re really asking: Are you engaged and curious?

This question is usually a sign that your interview is wrapping up. It’s also an excellent opportunity to show your interviewers just how prepared you were for the meeting while demonstrating your interest in the position and your knowledge of the company to help you decide if the job is the right fit for you.

Use this time to ask questions about the company, including any challenges it might be facing, how the company determines success in general or in your specific role, or what drew the interviewer to the organization and job. This is also a good time to build on topics that came up in your conversation to demonstrate your engagement in the interview or expand on topics covered in previous questions and learn what to expect next.
