Expedia Group Customer Service interview questions

I did not actually get an interview with Expedia however I had quite an experience. Recently they opened a Tier 3 customer service vacancy in Las Vegas, NV , me and one of my best friends applied. I have such a long experience with travel agencies for so long and specially in all the software and GDS travel systems that Expedia uses. All of those skills were demonstrated in the resume. I waited for any communication from their side but had none. Only my friend -who was also a previous subordinate of mine and has far less experience- got an interview and an offer and when I asked him he revealed to me honestly that he has a connection in the HR department who arranged it for him. I was so frustrated that I did not at least get that protocol regular courtesy email to tell me that they have reviewed my resume and chose to go with other candidates. After that experience I decided that I wont look for any opportunities in that company because the way their HR is handling their business does not make me comfortable working in such an environment.
