eLynx Technologies interview questions

The process starts with answering a recorded video interview online. Once done, I had two follow up interviews via Skype with staff from the Analytics team. They gave me a coding challenge to complete, and once completed I was invited for an on-site interview. The on-site interview was from 9am to 4pm, I was told that it ends with an interview with the CEO. I had a total of six interviews that day. By 4pm I was scheduled to meet the CEO, but it had been cancelled. I was informed shortly afterwards that there will be a panel interview the following week, and they will have me Skype in for it. I would get the details the following business day. That day came and went, and so I followed up via e-mail. After no response, and a few days later I received a generic rejection letter. I am usually fine with this, but in this case, I found it to be extremely unprofessional. I followed up twice, with no response from the HR or the Analytics team. The second time I followed up via e-mail. I received a generic rejection letter, one you would get if you were in the initial stages of the process. I was lied to about a panel interview that never came, and probably was never planned. I do not see myself working here, and wouldn't recommend anyone to relocate to Tulsa, OK to work with a staff that is unprofessional in their communication and behavior towards candidates. A total of 8 interviews (not including the initial video recording) were conducted and passing their coding assignment. I would say for a tech job, they do not know what they want.
