Every manager on file with a position
Largest first. Weight is the share of that manager’s whole reported book, which is the number worth quoting: $400m is a rounding error in one book and a defining bet in another.

What DDOG is worth
Knowing who owns it is half the question. The other half is what it is worth against the companies it trades beside, which is the one an interviewer will follow up with.
Build the comp set around DDOG →How much of the picture this is
A Form 13F reports US-listed long equity and nothing else: no shorts, no bonds, no cash and no non-US listings. It arrives forty-five days after the quarter ends, so a manager who sold in July still shows the position in a filing published in August. This page reads the managers on file here rather than every filer in the market, and each manager’s largest positions rather than the whole table, so a small position in a very large book may not appear. Say “their last filing showed” rather than “they own”, and the distinction will do you credit.
What to do with a name the funds are buying
Knowing who owns something is the start of a pitch, not the pitch. The next questions are what it is worth and why they were buying.
