It is not uncommon to experience some level of doubt or uncertainty when starting a new job. In your case, it seems like the new job is not providing the challenge you were hoping for, despite the attractive salary and benefits. It's natural to feel nostalgic about your previous company, especially if it offered a more demanding and fulfilling work experience. Before making any decisions, it is important to evaluate your current situation and consider a few factors. Firstly, assess whether the lack of challenge in your new job is something that can potentially change over time. Some roles may require a settling-in period before you are entrusted with more challenging tasks. If you believe there is potential for growth and development in your current position, it might be worth giving it some more time.However, if you have already given it enough time and you still feel unfulfilled, it may be worth considering other options. Reflect on what aspects are important to you in a job, such as the level of challenge, work-life balance, and growth opportunities. Use this self-awareness to align your job search with your preferences.While age can be a concern for some individuals, it is important to remember that it is never too late to make a career change or find a job that suits you better. Take the time to research and explore different opportunities that align with your interests and skills. Networking with professionals in your field or seeking guidance from a career counselor can also provide valuable insights and support.Ultimately, the decision to return to your previous company or search for a new job depends on your personal goals and priorities. It is essential to carefully weigh the pros and cons of each option and consider how it aligns with your long-term career aspirations. Remember, career decisions are not always straightforward, and it is okay to feel uncertain. Trust your intuition and make the choice that feels right for you.
