There is a website which allows job seekers to apply for jobs, and potential employers to chat with the job seeker if they are interested in him.
I had a similar experience with two potential employers over chat, and I am wondering if I did something wrong.
The discussions went on somewhat like this,
employer: Hi John Doe, thanks for applying ..... I would like to speak to you at 2 PM.... Thanks, Jane Smith.
As the employer was using professional email-like style, I too used a similar style and replied with the time that was suitable for me.
After this, in both cases, the employers replied in more casual manner
employer: How about 4PM?
As the employer used casual style, I too replied similarly,
After this though, I didn't receive the call from either of the employer. After a day, I replied again, this time using professional style, stating that I was expecting a call from them, but I did not receive any reply.
Sure! reply make them not call me, or I am thinking too much about this?
Note: The website shows the chats in its own web UI, as well as sends the messages over email. As I have had very few employers reply to my applications, I don't have any other experience to compare these incidents with.
