Infosys System Engineer interview questions

The selection process comprised of an Aptitude Test comprising of quantitative and verbal questions. After clearing the aptitude test I had a technical and HR interview. The technical interviews was more inclined toward coding stuff and was quite challenging while the HR interview comprised of behavioral questions. Aptitude Test comprised of good and challenging math questions, logical questions and verbal questions comprising of reading comprehension, fill in the blanks, correcting grammatical mistakes.

I dropped off my resume at a career fair. The representatives from Infosys were very crass and unpleasant, so I decided not to apply to any positions. However, they emailed me later saying my resume seemed like a great fit so they scheduled an online interview. During the interview there were two employees communicating from India via webcam. Neither introduced themselves. Both had broken English and I had to ask for questions to be repeated constantly. They asked me only trivial, basic technical questions, like "What is an integral?--What is a vector?--What is HTML used for?" even though my degree is in chemical engineering from a top 10 university in America and I have prior work experience involving coding. It was very clear that they did not look at any of the materials (resume, cover letter, transcript) they asked me to submit. I was asked no behavioral or work experience questions. I interviewed for four positions from my school's career fair and this was the only one that felt like a waste of time.
