At Looksharp, we do a lot of work to ensure the quality of our postings and make sure they are safe for students. That said, we can't be 100% perfect in removing all suspect companies. If the position does not feel safe or you suspect it is a scam, we recommend you stop the application process. You might ask the person to send you a link to their company website, and his/her personal LinkedIn account so you can learn more about the company and than see what they provide.
Please contact us with the name of the company and your concerns, and we'll do our own research. We'll take care of it.
