Teams interview, 30min...Unfortunately not a good experience. The manager was later for 5-10min. The interview started without her, only with a team leader. I was in the middle of my speech for a first question when the manager joined us. She distracted me, and I asked if I needed to start from the beginning, but she said no, just carry on. I stayed focused, not to panic after her such appearance. They asked what I'm planning for my future and I told that I'm looking for a company to improve and develop my skills, that my future goal to become a team leader and grow with a company together. They asked about my experience also. But the manager didn't have my resume with her. She wasn't prepared for the interview at all. She should have my resume and ask questions accordingly. But as she didn't, I had to really lead the interview while it's her job to do so. What kind of hiring manager doesn't have a resume of a candidate... After the interview, I sent a thank you email to the manager. After a few days, I was rejected and reason " over prepared" OVER PREPARED!! How that even possible! As a professional, a good memory and attention to detail are very important, especially for a specialist role ! Also, the agent told me that my thank you email put the manager off. She didn't appreciate my email. I'm sorry, but that is a very unprofessional hiring manager! Thank you email is a sign of maturity, appreciation, and show if interest. The hiring manager is very new to the business as I know she is not professional enough to lead the interviews. I felt robbed without giving me a chance. Maybe she felt threatened by my future goals... I'm very disappointed...As my values alight with company's values, I hoped to get a job at Sherwin Williams, I have a lot of experience required for this role and goals to grow together. It is sad that hiring a managers unprofessional job caused me a job.
