Interview Preparation Tips
Interview preparation tips for other job seekers - I always suggest staying away from these companies commonly referred to as WITCH (Wipro, Infosys, TCS, Cognizant, HCL). You will rarely encounter good interviewers there unless there is an extreme necessity. Interview was judging me on the basis of syntex by seeing in his phone. How can everyone write each and everything on copy. For the low level design first time in my 6 years carrier someone asked to design without using kafka or any other library like spring boot to achieve that add in reminder list problem 😂. At first it was my bad after holding a offer of almost 27 lakh I somehow agreed for giving interview. Second thing I also know that after Even clearing they cannot afford 30LPA which I asked. I just went there because from last 6.5 year I have never attended any walking or face to face interview so was curious for it. Currently also working with somewhat premium product development company only. My experience was very bad. May be it can get vary person to person.
