Leaving job within 2 months

Hello I was laid off in January (used work as a Product Analyst) and then I joined another company in March (also as a Product Analyst),

After working for a month I have understood that the only career pathway they offer is into a PM role whereas I want to grow into a data science role.

Wanted to get some advice on what to say in interviews for other companies when they ask why I am leaving so soon?
