Networking is necessary while working in a CRO space especially for those who are working in a hub of clinical research industry.
In order to build a strong network within your company, reach out to your colleagues and ask them for dinners and lunch, take them for a coffee that will be beneficial to develop a bond with them and they will support you in the hours of need whether you are looking for a higher position or an increment in your salary. People do not like and support those who reach out to them only when they need something as they think of them as selfish.
Another best way for networking is to attend meetings and company parties where you can meet recruiters, hiring managers, sponsors and directors of your CRO and through developing network with these personalities can help you to pursue your goals and for major career progressions.
These networks and relations with people are always magnificent especially when there are referral based opportunities and people refer you because of your qualities as they know you are capable, skillful and comfortable to work with.
