It's very possible. While everybody appreciates talent, it's very important to communicate well to your team members. When that falls off the track, things start falling apart.
Also, it's going to be hard to climb up the ladder in a firm, when communication is a problem. For instance, the person wouldn't be promoted to the role of a lead engineer or a role that faces your leadership. People in the leadership have very limited time and it's important to communicate to them crisply and briefly.
Imagine going to a meeting with Jeff Bezos, he's not gonna give more than two mins to even senior SVPs. That being said, bad communication shouldn't deter a candidate from applying. Everybody can pick it up :)
