They don't really specifically explain that you'd solely be doing on field sales during the interview, which can be misleading for people who expect the role to be more research/office-based.
As it's also sales, there's also a lot of pressure to meet the targets that they set you, not helped that how much you earn depends on how much sales you secured. If you're someone who would prefer to meet their own targets/goals at their own pace and wants a secure salary for peace of mind, I would not recommend this job.
