Last week, I discussed how you can get ready for your first day at work. This week, I am going to point at some mistakes that you should definitely avoid during your first day at work if you want to leave a good impression.

1. Not Paying Attention: This is your first day at work and you have to open all of your senses in order to familiarize yourself with the environment. You will get introduced to many people at your first day including your manager and peers that you will be working with. You will also learn the project you will be working on or your tasks in general. Therefore, you should pay enough attention to understand your responsibilities. Nobody expects you to learn everything from day 1 but it would be to your advantage if you carry a notebook and write down the important details. In this way, you can review your notes whenever necessary and increase your productivity.

2. Having a Know-It-All Attitude: Don’t try to show off on your first day. Nobody can know-it-all so try to learn. Come to the office with questions and not answers. Don’t try to criticize everything from the first day and don’t suggest a new alternative for the existing operations. You need to digest all the information first and fully understand the operations before proposing new methods. Moreover, nobody wants to work with a person who has an attitude so don’t be that guy.

3. Bringing Lunch from Home: Don’t bring lunch from home at your first day. Even if you had to bring lunch, at least don’t eat it alone at your desk because others may think that you are anti-social. In most cases, since you are a newcomer, you will be invited to lunch so go with them and socialize! Make some friends. However, don’t gossip during lunch even if your coworkers do. A friendly chit-chat is all you need at your first day.

4. Not Using Your Time Effectively: If you are given a task to complete at your first day and told that it needs to be done by the end of day, then, you better finish it. Otherwise, you may leave a bad impression on your manager. It is not good to sit around and wait until the last minute. Remember, you are hired to work so start immediately. However, if you feel yourself lost during the task, don’t panic. Instead ask for help and prepare some questions to get clarification. Finally, complete it to the best of your knowledge.
