This article compares the gpt4o and gpt4.5 models.

Given the prompt:

Based on the job description below, prepare 10 interview questions.

----
Senior Web Application Developer

Qualifications:
Bachelor's degree in Computer Science, Software Engineering, or related field.
4+ years of experience in software development
Experience in developing at least 2 commercial applications within the past year
Malaysian citizenship.

Requirements:
Proficiency in Ruby, Go and/or Python languages.
Familiar with 1 or more web application frameworks.
Familiar with Github Actions, Bitbucket Pipelines and/or Docker.
Experience with AWS products and services is a plus.
Excellent communication in English, both verbal and written.

My Observations:

1) GPT-4o jumps straight into technical skills, but GPT4.5 starts with a broader topic.

GPT4.5 version would be what I would likely use. Although the JD requires specific skills, listening to the candidates' experiences is also beneficial. The answer to this question would give the interviewer additional context of the candidate. (E.g., their role, historical tech stacks). GPT-4o's version has this question toward the middle of the interview, which is slightly too late.

2) When asked about technical skills, including languages and frameworks, GPT-4o wants the candidates to provide some past projects. The candidate would likely give a similar list of projects in both questions. One would usually be most proficient in a framework in which they have equivalent language proficiency.

GPT-4.5, on the other hand, asked for an example of problem-solving with a programming language. And for framework, it asks for candidate's preferences and the reason. This structure would make it possible to "dig" more information from the candidate.

3) The questions for CI/CD and cloud products are OK. Both models provide decent questions.

4) The communication skill question is interesting. Both models ask relevant questions about effective communication, while GPT-4o emphasizes communication in "English". This could be caused by the "English" requirement in the original prompt.

While there is no right or wrong, it is not useful to include "excellent communication in English" here. The interviewer can already judge the English level in the interview process itself.

5) Both models produce questions not directly listed in the original prompt. I would pick my questions from both lists.

I like the last question provided by GPT-4.5. It is a good conclusion to the interview.

Conclusion

Both models understand the prompts well enough to produce decent responses. GPT-4.5 shows additional capabilities below:

• It structures the questions in a more natural (human) way. It starts with a more generic question and ends with a question that gives the candidate a chance to express supplements that weren't discussed earlier.
• Its output does not repetitively ask for "give an example of". It probably has considered the list of 10 questions as a whole instead of generating 10 separate questions and combining them.
• And it is very expensive to use! :)
