Pre-MBA career path / job description at elite Growth Equity Firms (General Atlantic, TPG etc)

What is the job like for pre-mba analysts/associates at the above mentioned firms? I assume they are doing a lot of modeling as well as some sourcing and due diligence?

I've looked at the backgrounds of many pre-mba employees on linkedin and they seem to share similar backgrounds to folks at UMM or MF PE i.e. top undergrad straight to firm or some combination of 2 years banking and/or consulting. Is getting a job at Growth Equity firm such as GA ,TPG, BX etc. just as hard as breaking into their PE groups?

What is the pay like at these growth equity firms compared to PE firms? I assume it's pretty similar. Seems like there are many firms that even do both - e.g. Blackstone starting up its growth unit recently.

What are the main reasons people choose to go into Growth instead of more vanilla PE? I assume the industry is much more heavily focused on tech. Also seems like there would be more to the job than modeling, but I'm not sure.

I'm an undergrad currently considering trying to break into Growth Equity after hopefully securing an ibanking internship. What else should I know about the industry vs standard PE/IB.

Thank you in advance for any comments.
