Started with tell me about yourself, asked questions extensively from internship/projects. Generally, they have one extempore as well but, in my case, they picked up from my 'online' training on digital marketing which I had mentioned in my CV and asked me to speak on the topic after giving couple of minutes to think. Be thorough with your CV. They did ask technical questions but again from the final year project and internship ex. It is also good to review the points shared during the pre-placement talk and align your 'why to join' with theirs. I saw LnT as a company which would give me an opportunity to practice what I learned during engineering and let the interviewers know this enthusiasm clearly. It is okay to not know some technical questions, as the screening test is of moderate difficulty and you would only come to the interview stage post that. Thus they know that your technical knowledge is sound!
Prepare well for the screening test, they use their own software for online test, and it tends to have certain issues while giving the test, if it detects noise, camera misalignment etc. In our time the test was again scheduled for the students who faced technical errors during first time.
