Complete misalignment when it comes to sales career. Management focuses too much on making sellers do administrative work - answering support calls, dealing with cancellations. It takes away time from selling.
Monthly quotas are extremely short sighted. All real software companies have annual or quarterly sales goals. You aren’t allowing your sellers to think strategically and grow customer relationships for larger deals.
Zillow promotes employees to managers who hit sales quota, most don’t make good managers - they have no experience coaching or advising rather just focus on looking good to upper management.
