  3. We will share your activity on the Day of Photonics LinkedIn page
  4. Collect reactions for this post (any means counts!) until 27 October, 2022 inclusively
  5. We will calculate all the reactions including: comments, likes, shares (e.g. if some person will like, share and comment on the activity, it will be treated as 3 reactions)

    *if you do not see your activity posted on our LinkedIn page within 48 hours after your post, please send us the link of your post to
  7. NOTE: we will be sharing only 1 post for the challenge, so please select the best on to participate and add hashtag and mention our account. If you want to share more post about your activity, feel free to do that, but then do not put the hashtag and do not mention our account, because by doing this we understand that we need to repost this post. It is also not good for you that we repost too many posts related to your company, because then you do not know which post should you collect the reactions on. Thank you for your understanding.
