Guidehouse Data Scientist interview questions

The interview process was 3 rounds. The first being technical/ behavioral with the manager, second being a live Python evaluation and last was meeting with CIO. Must have proficient knowledge in Python and Machine Learning

The interview questions were average and the interviewers were nice, and after all the interviews they told me that I got the offer. However, the HR sent me another job offer with quite different requirements and much lower pay grade than the original job I applied for. Also, then I noticed the requirement for citizenship for this job, which was not asked during the application. The HR is also really poor at communicating these points and ignored my emails several times. Beware of this company.
