Is this thumbtack.com pop-up modal allowed by Google?

When you click on a Thumbtack organic result, there's a pop-up modal on the landing page. Is this allowed by Google?

E.g. Go to these SERPS and click on the first Thumbtack result. The landing page has this modal appear. Is this likely to hurt their rankings?

The interstitial update only affected mobile browsing, from what I can remember. This popup doesn't appear on their mobile site and thus, I would assume it shouldn't have any impact. However, I would recommend increasing the wait time to pop the message up,  so that it acts as a form of help to a user, rather than blocking their browsing immediately.
