This is a sign of extremely poor management, if your manager is constantly asking for updates and interrupting you, then look for another place ASAP, because either the company is dying or your manager is incompetent ... or both
Companies - even apparently successful companies - still love to destroy productivity with a constant stream of interruptions (email, teams, slack, etc.) which must be responded to immediately in order to maintain employment.
Yep poor management cannot tell the difference between busy and productive - pure unproductive busyness gives the illusion of progress, so as the demands for output increase, they often slow things down even more!
