you get pre assignment with mcqs and a coding challenge which you have to complete within about 3 working days, then you get technical interview with a Senior Technical Manager

First I had a telephonic interview for around 20 minutes. After that, I got the call for the second interview in their office with their senior software engineers, which was of around 1 hour. The second interview went well and I got the call of the final technical interview with their project managers. After clearing all the technical rounds, I was invited for the HR interview with senior HR. The HR was so rude, she asked me a lot of irrelevant questions about my family members. It made me feel like it's my family member's interview instead of mine. She should learn how to treat with the candidates. You are hiring them no buying them. After HR interview, I got the offer with the designation of Software Engineer Level 2. They should have asked me before HR interview that if I would be interested in the SE designation because the vacancy was for Senior Software Engineer. They were informing me about the designation while they were giving me offer. I rejected the offer After few days, their Senior HR contacted me on linkedin for the same vacancy because they didn’t know that I am the same person who has given interview few days ago. How unprofessional, they don’t have any record of the recent candidates. They should work on HR department, really very bad impression on me.
