2 rounds of phone interview, the first round was conducted by the HR. The second round was conducted by the senior manager who I worked direct under. The interview is pretty personable and relaxing, mainly to check if you are a team player and have some basic understanding in tax. Maintaining a positive attitude is crucial for this interview. You should also negotiate your salary when you get the offer. There's a chance that you make more per hour if you negotiate and demonstrate you are a valuable person for the company.
