it was a 4 round process. i completed 2 rounds but technical interview was a bit tough. They look for a extra ordinary person with hight technical skills. 1)Aptitude and basic Linux question 2)G.D. 3)Technical interview 4)Manager round

I had initially interviewed for an entry-level position, which I turned down because the pay was laughably low. After I did that, Red Hat got back in touch with me about a senior position with pay more commensurate with my expectations. At this time I had another offer on the table, but I decided to go through with their interview anyway. Boy that was a mistake! They brought me on-site, showed me an org chart that included where I *would* be working, went through a few more interview motions, then asked me if I was still interested. I said yes, but I need to make up my mind between them & the other company soon. They said they'd have an offer ready to by the beginning of the following week. Well, Monday went by with no reply. By Tuesday, I was making phone calls & sending emails asking for an update and reminding them that I had a deadline to meet. Wednesday evening around 6 PM, I finally received an email from them saying that they'd decided to go with another applicant. I was SOOO mad at them, not because I didn't get the job, but because they almost cost me the other position; I had to string them along waiting for Red Hat to get back to me so I could make my decision. Red Hat lied to my face during the interview, and I can only assume tried to keep me from landing the other position out of spite. It is the worst employer I have ever had the misfortune of encountering.
