Applied to two position, and was informed that one position was fully filled. As a result, I was moved to another position that has not been filled. I spoke with two recruiters on the phone in a time span of 2 weeks. The first recruiter was professional, she asked basic questions about my background and experience, as well as informed me about the assessment that I did online. The second recruiter, on the other hand, was not professional. He was not very courteous and made me felt like he was just checking off list. Firstly, he asked me about job duties/responsibilities that I clearly listed on my resume/application. Secondly, he asked me if I had applied with other companies, I felt like any reasonable recruiter would know the answers, but to flat out asking that question just showed the unprofessionalism. Thirdly, I had obviously not done well on the phone interview, and he proceeded to move me onto the next round, which was an assessment. I had already completed an assessment, so I did not know the purpose of having another assessment. In addition, the phone interview was very unorganized. He assumed that I was available and I should proceed taking the assessment during the phone interview. I just wanted to point out that the phone interview was schedule to be around 15-30 minutes, by the time we reached the assessment portion, it had already taken close to an hour. I asked if it was possible to do the assessment on a later date, the recruiter did not even know when he had an availability. He then stated--"We can do it on the following Monday at 10am (We had the phone call on Tuesday)." I accepted the time and he then stated--"there will not be an email or any confirmation, just make sure to pick up the phone around that time." I acknowledged and we ended the conversation. In less than 5 minutes, he called back and said the time would not work and we had to do it on Thursday at 10am (two days later basically). I accepted and continuously felt like I was treated very unprofessionally by him. Thursday came around and I noticed him calling me at 9:20am, which made me realized that he completely disregard the time that we had set up. After the situation, I decided to not proceed with the interview process due to several unprofessional incidents.
