The most comprehensive bank Interview Answer Review tooling available online.

The last conference I attended was the Open Source Security Foundation. As I was leading the Dart & Flutter security program I wanted to learn about the innovations, tooling and services that other open source projects were using.

There were interesting conferences for tooling to sign artifacts with a single command and how the open source community was working in tooling to build, sign and release artifacts in a secure way for everyone using GitHub.

I learned that there were many technical innovations that I could use to speed up the Flutter Security Program, for example implementing secure build workflows using github actions. I also met several people working on similar projects and took the opportunity to share our lessons learned and challenges. Later on the connections with the open source security foundation proved very useful during technical reviews and collaborations.

def can_be_equal_with_one_swap(s1, s2):

    # Step 1: Check if lengths are the same

    if len(s1) != len(s2):

        return False

    # Step 2: If strings are already identical

    if s1 == s2:

        return True

    # Step 3: Find mismatching positions

    mismatches = []

    for i in range(len(s1)):

        if s1[i] != s2[i]:

            mismatches.append(i)

    # Step 4: Check the mismatch condition

    if len(mismatches) == 2:

        i, j = mismatches

        # Check if swapping the mismatched characters makes the strings identical

        return s1[i] == s2[j] and s1[j] == s2[i]

    # If there are not exactly two mismatches, return False

    return False

I was working with 5 customers at once, and had to focus on those activities where I could make a difference, make the most impact, that I could not delegate, and where I could balance with other priorities - in order to do that, I measured the priority of the tasks by the cost of delay, in other words, the impact of not doing them at that time. Then, with more clarity about the priorities, I thought which ones I could delegate to other team members, and if that made sense, with the required support and guidance from my side. Working as a team and not trying to get everything done yourself is key in the long term with multiple, competing priorities. Then, organizing my time well in short, focused timeslots for the most important tasks, made a difference.
