There are a lot more free apps out there, never heard of this one though. Might want to do a search and try something else.  If they are sending stuff via text, then you can do the following:

For text messages: forwarding any text message spam you get to the short code  “7726,” which spells “spam” on most phones, to alert your network operator to the abuse. ATT won't accept 7726 But they will accept BLOCK and return a message that the web site is blocked. forward the texts to 7726 or BLOCK, depending on your phone carrier.

I didnt get this number. I got a text message from 650-419-5748 that they would like to talk to me regarding my recent job search.  Umm has anyone gotten this mensaje by any chance.

Same thing happened to me when I applied at McDonalds. Sends you to another site with career and schooling questions and never got to application through that site.  I am not calling this number.  How unprofessional!

Do not call

I am getting this same text every single day for over a week now. If a job wantedcme that badly, or if at all, that would CALL AND NOT TEXT. This is a 100% scam. Dont even reply with a call or text. A text could send a virus to your phone, and a phone call gives them instant demographic info even if you dont say a thing.
