Q3. Which company did you work for?
Ans. I worked for a startup founded by IITians. The company age is 5-10 years and around 50 employees. The HR (Nikita Deshmukh) declared it as a fake company. This defaming behaviour by her was so rude and it's even reflecting how she is creating a bad image of the company she works for. It should be noted that every company was a startup before it turned into an MNC.
