Make the list of candidates that you saw on Google or were told about. Explore their testimonials and check case studies. The latter may tell you a lot about a company’s reputation and image on the market.
If big, recognized businesses cooperate with the product engineering company, it points to their reliability and trustworthiness. However, if a company has little to show in the portfolio, it may be a sign of lacking experience. In this case, exclude the candidate from your list.
The next step is to get in touch with a partner. Pay attention to the following factors:
promptness of response;
clarity of communication;
friendliness;
transparency.
These are the factors that fully demonstrate the professional level of your candidate. Analyzing them will help you choose the best partner from your list of product engineering services companies.
