Is it a red flag someone has too many skills listed that they have never used in production? ( Less than 2 YOE)
Do gou guys mention skill levels ? Or is it understood ( like you have used XYZ tools listed in workexp pointers while ABC tools listed and used in projects so obviously you won't have that much depth in ABC)
I have used :
SQL, DBT, BI Services in work and buily end data models + pipelines for OLTP systems . Also worked with some ML stuff
AWS, Databricks, Airflow , PySpark in projects ( project using modern stack)
I have 1.5 YOE, preparing for a switch . How should I position myself? My end to end projects are fine I guess but GPT told me recruiters will question my credibility if I list too many skills I haven't used in production
If you have too many skills across across different technology areas - across web backend, frontend, devops, cloud, cybersecurity, data engineering, ML/AI, that kind of resume will raise questions if you don't have the matching experience. (Those kind of resumes are more expected from people in Staff, Principal, Architect roles, who have worked across all those different technology areas during decades of experience.)
In your case, I see that you really don't have "too many skills", and all your skills are clustered around a couple of narrow areas - data engineering & data science. So mentioning them shouldn't be a problem at all.
Also, don't worry about what or what not you have "used in production". Developers do most of their work in development environments, and in many organizations, developers don't even have access to production environments (that is reserved for cloud administrators & SRE teams only), due to data protection and privacy concerns.
So you don't even need to mention to anyone, what or what not you have "used in production", or even make that distinction. Just say that you got a chance to work with all those technologies at your previous job. That is enough. But keep a mental model of how each technology was being used in the company, and for what purpose.
As long as you know those technologies well (that you mentioned above), and can use them effectively at your next job, you should be okay if you mention them on your resume.
Good luck for the job interviews! 👍
One caveat though, don't go around mentioning technologies that you don't know well, and can't justify it in the technical interviews.
Anything you mention on your resume is fair game for questions in interviews. If you mention some technology, but aren't able to answer technical questions about it in interviews, then that is going to be a negative point, and may cause you to fail in interviews.
Tailor it to the job you are applying.
