Donato Technologies interview questions

First I applied to the position on Indeed. I then got an email listing 36 different jobs, asking me to choose one. After selecting the appropriate job someone almost immediately called me and we talked about the position. They told me that I needed to add specific verbage to my resume saying I have done X or Y. Even though I told them that is not something I have experience in they told me its fine, they want this so just add this to your resume and send it back. I was reluctant but did it anyway as it wasnt something I couldnt quickly learn. They called back offering a different position instead as the one I chose didnt meet my required pay. This is where things got weirder. I kept getting constant phone calls from 2 different people. Every time I responded to an email another immediate call asking for me to urgently modify my resume again and again. This entire time I continued to receive the same canned email with name placeholders from them about "multiple positions available" repeatedly in the same day. At least 4 times Its the shadiest recruiter I have ever talked to and I just stopped answering their calls. Too many red flags.
