Thank you so much for your feedback; it%E2%80%99s incredibly valuable to us. As we%E2%80%99ve scaled, Slack has looked very different at 100 employees than we have at 500 or 2,000 employees. Regardless of company size, focusing on hiring great people and listening to everyone%E2%80%99s perspective is and always will be a top priority for our leadership team. As we grow, we also want to foster an environment of constant learning, a big part of which is providing useful feedback to our peers, managers and direct reports alike. Thank you again for sharing.
