When asked the strength/weakness question you don't have to struggle.
Answer it by going back to your last employee review and see what improvements your boss suggested. Mention what your boss thought you needed to improve upon and talk about the actions you took to improve.
Hiring Managers ask this question really to see if you are trainable and how you respond to constructive criticism.
If you want to look for a job without tipping off your current Employer. Here is a good tip:
CREATE YOUR PERSONAL BRAND USING SOCIAL MEDIA-Talk about your areas of expertise, share your accomplishments in your role, write content to show your knowledge and share it on Social Media especially Linkedin.
This will get you noticed by Recruiters who will reach out to you for job opportunities.
When interviewing try to find ways to interject in the conversation how you took initiatives on projects, problems you identified and more important the solutions you recommended to solve them.
Something great to show is ways you were able to take responsibilities off of your bosses hands so they could be more efficient with their time.
In starting your Job Search don't overlook the power of Alumni Relationships both College and High School.
There is a pride dynamic that people have with affiliating and helping someone who went to their school.
Linkedin has a Alumni Search function to help you find people across the World who went to the same school as you. Don't be afraid to reach out to those people even if you didn't know them. It's an automatic "WARM LEAD".
Video Resumes are a great way to get a job applicant's "foot in the door" for any type of job, but especially for Critical Roles to a Company such as Sales, Technology, Leadership, HR and Marketing!
What a 3 minute clip can accomplish highlighting a Candidate's background in a very vivid and visual way to an employer far outweighs a multiple page Written Resume.
