Salespeople often too young and inexperienced
I'm seeing more and more young people being hired into sales roles, which is great but companies are then not educating them on how to interact with clients well and how to understand client businesses and industries to a decent degree. This then means that customers aren't satisfied with their interactions with salespeople and rely on them less, contributing to the trend towards marketing, which a few people can control and orchestrate centrally. Companies need to really invest in a mix of experienced sales people and younger grads so that there is a real transfer of knowledge and skills, as enterprise hardware sales people are expected to be experts in their products and customer industry, but are often nothing more than tin shifting call centre staff with little investment behind them.
