Hello sir, i recently saw your videos and started following you. I am working with Cognizant since 2022. I am on bench as my project ramp down. I am a 7 years experienced professional. I didn't get any project yet and its been 35 days now. Today i got mail from hr that we will give additional 6 days and within that if i didn't get into a project its my mistake. I pinged almost 90 project managers for project opening. But very responded and i didn't get any project. Many project i applied were rejected as the so got cancelled. I have tried my bast to get mapped to a project. But they didn't arrange anything to allocate and now they are threatening. What should i do

@interviewhappy

5 ай бұрын

I can completely understand your situation. 2 things you should do now 1. Try reach out to the managers who handle projects in your skills(ask your previous manager for any reference or account level other project). 2. Most importantly, start looking outside and be ready for internal and external interviews. (Ask HR to give you some more time and in worst case of notice period, don't let any HR to shorten your notice period)

Hi buddy, 3 things you must try: 1. Make sure to give more focus to .NET Core and web api in your resume in your latest project(even if it is in some other tech stack). Add them in your skill set also. 2. Refresh your resume in job portals every week(companies pick only latest resume). 3. Still not getting call, just reduce your notice period to 15 days, check if then you are getting calls. Most importantly HAVE PATIENCE & KEEP PREPARING, don't let any excuse for the day when you get the call. Sorry, but due to my work schedule I can't do one to one discussion. All the best for your career.
