Programmers train large language models (LLMs) on enormous swathes of data, which gives artificial intelligence (AI) models the capability to understand patterns and extract meaning from human language in a highly sophisticated way. LLM-based AI models can then reproduce human language in the form of new data outputs, often in response to user prompts.听

LLMs are a highly complex, integral part of modern AI technology. Make sure you鈥檙e prepared for your LLM interview by reviewing the following 13 common interview questions.听

13 common LLM interview questions

While questions will likely vary from interview to interview, practicing your answers to some of the following common questions can be important preparation.听

1. What is a large language model (LLM)?

This is an elemental question you are likely to get in most, if not all, LLM interviews. Answer succinctly with something like this:聽

• LLMs are AI models developed to understand human language.

• LLMs allow computers to comprehend and replicate human language.听

• LLMs use machine learning (ML) to power popular interactive AI technologies such as ChatGPT.听

This last answer shows you know a bit about what people actually use LLMs for in the real world. It also implies you have some knowledge of ML, the key technology behind applications such as chatbots.听

Other forms this question might take:聽

• What are the basics of LLMs?聽

• Could you explain what an LLM is in plain language?聽

2. How do you train LLMs?

Building on the knowledge of ML displayed above, you can discuss further how much you know about the components of LLM training. You can mention that programmers train LLMs with massive amounts of data. LLMs learn to predict outputs based on the likelihood of one word or phrase following another.

If the interviewer wants more detail, consider mentioning these three common training modalities:聽

• Few-shot learning

• Fine-tuning

• Zero-shot learning

The interviewer is looking to make sure you have the proper technical know-how for the job, yes. But they aren鈥檛 necessarily just testing your technical prowess. They鈥檙e evaluating your communication skills鈥攊.e., the extent to which you can explain difficult concepts to a general audience.

Other forms this question might take:聽

• How do you prefer to train LLMs?聽

• What does your LLM training process look like?聽

• How did you train LLMs in the past?

3. What are the key components of an LLM architecture?

The interviewer is asking this to gauge your familiarity with key LLM concepts such as:聽

• Attention mechanism

• Data sets

• Deep learning

• Neural networks

• Transformer models

You can be confident here: These are key to LLMs, and you likely know this material very well.听

Other forms this question might take:

• Can you tell me about the key components of LLM?聽

• What are some components of LLM architecture?

4. How do LLMs generate text?

It might be helpful to use an analogy to answer this question: LLMs are something like giant autocorrect features, predicting the most likely next word or phrase based on patterns in the data they were trained on. They can be fine-tuned or retrained with updated data to improve their accuracy and relevance over time.

Let the interviewer know that you understand the applications of LLM text generation vis-a-vis the job for which you鈥檙e applying. Depending on what the company does, mention LLMs鈥� text generation capabilities in terms of:聽

• Answering customer questions

• Language translation

• Text summarization

Other forms this question might take include:聽

• What鈥檚 the method behind LLM text generation?

• How do LLMs generate different types of text?聽

5. What are the challenges of training LLMs?

LLM training is highly sophisticated. An interviewer may want to know that you understand certain challenges inherent to LLM training.听

Mention that LLMs tend to be costly, both to develop and to operate. They鈥檙e also highly complex and trained on so many data parameters that they can be vulnerable to:聽

• Bias

• Inaccuracies

• Hallucinations

It鈥檚 important that you show your interviewer that you understand that, as valuable as LLMs are, they aren鈥檛 perfect.听

Other forms this question might take include:聽

• What are some drawbacks of LLMs?聽

• What risks come with the use of LLMs?聽

• In what areas can programmers improve LLMs?聽

6. How can you use LLMs in various applications?

By this point in the interview, you鈥檙e discussing the real-world applications of LLMs rather than just how they work in theory. Mention key use cases such as:聽

• Text classification

• Text completion

• Text generation

• Text summarization

• Text translation

It may be a good idea to discuss some key concepts of natural language processing (NLP) at this point. NLP is, after all, largely responsible for the leap in language understanding LLMs can make.听

It鈥檚 also worth mentioning the value LLMs have in computer vision tasks鈥攕uch as assisting with image captioning, image classification, and object detection鈥攕o that your interviewer knows that you understand the wide variety of use cases LLMs possess.

Other forms this question might take:

• What are some LLM use cases?聽

• What can the average person use LLMs for?聽

• What kind of language tasks are LLMs sophisticated enough for?聽

7. What is the role of attention mechanisms in LLMs?

Programmers train LLMs on enormous data sets that, in many cases, naturally feature biased or noisy material. Your interviewer will want to know that you understand how to filter that out.听

One way of doing so, of course, is via attention mechanisms鈥攁n ML technique by which neural networks focus on the most important specific portions of input data. Knowledge of attention mechanisms shows an interviewer that you鈥檙e dedicated to discovering ways to improve LLM performance.听

Other forms this question might take:聽

• Why do you use attention mechanisms in LLM training?聽

• When would you introduce attention mechanisms in an LLM?

• What happens to an LLM in the absence of attention mechanisms?聽

8. How can you fine-tune LLMs for specific tasks?

As you already went over how to train LLMs; the question now is how you fine-tune an LLM post-training.听

Focus on discussing how to fine-tune pre-trained LLMs to perform specific tasks. Discuss techniques such as:聽

• Full fine-tuning

• Instruction fine-tuning

• Parameter-efficient fine-tuning

Make sure to mention task-specific fine-tuning, keeping in mind the company鈥檚 specific domain. This signals to your interviewer that you鈥檙e already thinking in a practical way about your day-to-day work as a prospective LLM employee.听

Other forms this question might take:聽

• How do you prefer to fine-tune LLMs?聽

• How would you fine-tune our company鈥檚 LLMs?聽

• Is there a best way to fine-tune LLMs?聽

9. What are the ethical implications of using LLMs?

Your interviewer wants to know that you are aware of the concerns many people have about LLMs and different forms of AI.听

This is a great opportunity to discuss how the company trains its LLMs, where it gets its data, and what it does to protect it鈥攊n other words, its data governance strategy.听

Remain upbeat while you and your interviewer talk about issues surrounding:聽

• Bias

• Data quality

• Data tagging

• Masking

• Tokenization

Talking out the ethical issues associated with LLMs doesn鈥檛 show you鈥檙e a cynic but rather that you鈥檙e a conscientious technology professional.听

Other forms this question might take:聽

• What are some objections to using LLMs?聽

• What are your concerns regarding big data and LLMs?聽

• Could you describe why someone might worry about using LLMs?

• Choose an appropriate LLM framework

• Continuously monitoring a model's output

• Define your evaluation metrics

• Fine-tuning for domain specificity聽

• Leveraging retrieval-augmented generation (RAG)聽

• Set up security guardrails

Your interviewer won鈥檛 expect you to set up an optimization program for their company鈥檚 specific LLM needs on the spot. They just want to know that you鈥檙e considering how you might do so in a general way.听

Other forms this question might take:聽

• How can you improve an LLM?

• What can you do to maximize LLM reliability?聽

• How can you pre-empt LLM difficulties?聽

11. What is the future of LLMs?
