I understand that <Company> has likely made financial and logistical decisions based upon the expectation that I would be following through on the acceptance of my offer, and therefore I feel it's necessary to formally apologize for any inconveniences I have caused as a result of this.
I want to thank you personally for helping me along this processes and also apologize if this in any way negatively affects your situation as my recruiter.
I genuinely hope we can work together in the future, and I have nothing but positive things to say about <Company>'s internship process. I will continue recommending my peers to apply to your company, and I wish you all the best in the future. - Taken from googlers discord, take boeing its really easy to twist your role into swe
