Accepting or rejecting an offer
Accepting an offer is quite simple. You need to inform the company that you accept the offer and discuss details such as the starting date (especially if you need to work a notice period at your current workplace), paperwork, reallocation (if it is the case), and so on.
Declining an offer is a bit more of a delicate situation. It must be done in a way that allows you to remain in good relations with everyone. The company has invested time and resources in the interview, and so you have to decline their offer politely. You may also, after a while, consider applying to the company again. For example, you can say something like I want to thank you for the offer. I was impressed with your company and I enjoyed the interview process, but I’ve decided it’s not the right choice for me right now. Thank you again, and maybe someday we will meet again.
There are some cases when you need to manage multiple offers. While you accept an offer, you have to decline another. In the IT industry, it is very important to build contacts and maintain them over time. People frequently change their jobs and positions, and in this dynamic environment, it is important to not squander any contacts. Therefore, don’t forget to call the hiring managers (or the contact person) that made you an offer and inform them about your decision. You can use the same phrase given previously. If you cannot call, then send an email or go to the office to meet them in person.
