I received a phone call from a company, claiming to have an interview in 58 cities. She called from her landline and said that she saw my resume and asked me to go for an interview tomorrow.
It's true, don't worry. The recruiting unit saw your resume in the same city of 58, and all of them made phone calls through 58. Some of us are looking for jobs, and they all call from landline. It's all true. Don't think too much. But be careful, there are many liars now. Just tell the truth yourself.
